Need to implement the TCP Socket transport method needed to send GX files to the printer.

How it works (reverse engineered with wireshark):

(Tested on the Flashforge Finder)

1- Send this command: 'M28 {file_size} 0:/user/{file_name}.gx'

(Max length for file_name is 36 bytes, in case it's more truncate it.)

2- Then slice the file in 4080 bytes sized chunks, then add 16 bytes at the beginning of each chunk, making it a 4096 bytes sized chunk. Aftert that send only one chunk each time.

The first four bytes should be 0x5a, 0x5a, 0xa5, 0xa5.

Next four bytes should be a four byte unsigned big endian counter starting at 0, incrementing each chunk.

Next four bytes should be a four byte unsigned big endian data length (that length being 4096, representative of each chunk, except last for the last chunk which may not be 4096).

The last four bytes should be a big endian CRC32 of the data for that chunk.

That should make a 16 byte "header".

Then the add rest of the chunk in the rest of the available the bytes, making it 4096 bytes in total per chunk.

The last chunk has to be padded with 0x00 until the data length is 4096 bytes because it may not be the full size. The CRC on the final chunk is for the data without the padding.

3- Send the commands in sequence 'M29', 'M23 0:/user/.gx' to start printing.

All commands can be sent using the already existing socket code within the API.
