Release 2.0.0rc1

Tokenizer support for Gerber X3 syntax:

- [x] G04 - Comment - A human readable comment, does not affect the image.
- [x] MO - Mode - Sets the unit to mm or inch.
- [x] FS - Format specification - Sets the coordinate format, e.g. the number of
      decimals.
- [x] FS (Deprecated modes)
- [x] AD - Aperture define - Defines a template-based aperture, assigns a D code to it.
- [x] AM - Aperture macro - Defines a macro aperture template.
- [x] Dnn (nn≥10) - Sets the current aperture to D code nn.
- [x] D01 - Plot operation - Outside a region statement D01 creates a draw or arc object
      with the current aperture. Inside it adds a draw/arc segment to the contour under
      construction. The current point is moved to draw/arc end point after the creation
      of the draw/arc.
- [x] D02 - Move operation - D02 moves the current point to the coordinate in the
      command. It does not create an object.
- [x] D03 - Flash operation - Creates a flash object with the current aperture. The
      current point is moved to the flash point.
- [x] G01 - Sets linear/circular mode to linear.
- [x] G02 - Sets linear/circular mode to clockwise circular.
- [x] G03 - Sets linear/circular mode to counterclockwise circular.
- [x] G75 - A G75 must be called before creating the first arc.
- [x] LP - Load polarity - Loads the polarity object transformation parameter.
- [x] LM - Load mirroring - Loads the mirror object transformation parameter.
- [x] LR - Load rotation - Loads the rotation object transformation parameter.
- [x] LS - Load scaling - Loads the scale object transformation parameter.
- [x] G36 - Starts a region statement which creates a region by defining its contours.
- [x] G37 - Ends the region statement.
- [x] AB - Aperture block - Opens a block aperture statement and assigns its aperture
      number or closes a block aperture statement.
- [x] SR - Step and repeat - Open or closes a step and repeat statement.
- [x] TF - Attribute on file - Set a file attribute.
- [x] TA - Attribute on aperture - Add an aperture attribute to the dictionary or modify
      it.
- [x] TO - Attribute on object - Add an object attribute to the dictionary or modify it.
- [x] TD - Attribute delete - Delete one or all attributes in the dictionary.
- [x] M02 - End of file.

Tokenizer support for **DEPRECATED** Gerber features:

- [x] G54 - Select aperture - This historic code optionally precedes an aperture
      selection Dnn command. It has no effect. Sometimes used. Deprecated in 2012.
- [x] G70 - Set the 'Unit' to inch - These historic codes perform a function handled by
      the MO command. See 4.2.1. Sometimes used. Deprecated in 2012.
- [x] G71 - Set the 'Unit' to mm - This is part of the historic codes that perform a
      function handled by the MO command.
- [x] G90 - Set the 'Coordinate format' to 'Absolute notation' - These historic codes
      perform a function handled by the FS command. Very rarely used nowadays.
      Deprecated in 2012.
- [x] G91 - Set the 'Coordinate format' to 'Incremental notation' - Part of the historic
      codes handled by the FS command.
- [x] G74 - Sets single quadrant mode - Rarely used, and then typically without effect.
      Deprecated in 2020. (Spec. 8.1.10)
- [x] M00 - Program stop - This historic code has the same effect as M02. Very rarely,
      if ever, used nowadays. Deprecated in 2012.
- [x] M01 - Optional stop - This historic code has no effect. Very rarely, if ever, used
      nowadays. Deprecated in 2012.
- [x] IP - Sets the 'Image polarity' graphics state parameter - This command has no
      effect in CAD to CAM workflows. Sometimes used, and then usually as %IPPOS\*% to
      confirm the default and then it then has no effect. Deprecated in 2013. (Spec.
      8.1.4)
- [x] LN - Loads a name. Has no effect. It is a comment. Sometimes used. Deprecated
      in 2013. (Spec. 8.1.6)
- [x] Combining G01/G02/G03 and D01 in a single command. (Spec 8.3.1)
- [x] Coordinate Data without Operation Code. (Spec 8.3.2)
- [x] Style Variations in Command Codes. (Spec 8.3.3)
- [x] Format Specification (FS) Options (Trailing Zero Omission, Incremental Notation).
      (Spec. 8.2)
- [x] Draws and Arcs with Rectangular Apertures (Spec. 8.2.3)
