Extend node-mbus library to allow sending a custom frame to a slave meter

[entagy]

Hi,

Thank you for creating this very useful library, however, it would be super useful to have a function that allows sending a custom frame to a secondary slave.

I have a CMex40 M-bus master connected to a breaker device which I need to turn on and off by sending it a simple frame 01 fd 1a 40. How can this be achieved with this library?

I appreciate the help as I am only a beginner developer learning nodejs but found no other library that handles m-bus communication.
