New HTTP AT Command structure for compatibility using the LARA R6001D

Reference Doc for HTTP AT commands for LARA R6001D
https://content.u-blox.com/sites/default/files/documents/LARA-R6-L6_ATCommands_UBX-21046719.pdf

Current AT commands were designed to run with the SIM800H module. Upon reviewing the documentation for the 4G module, new AT commands need to be added in a separate function to achieve the same output. The current version is incompatible with the 4G board.

Reference document has been provided above.
