feat: View Raw Messages

[AarjavJain101]

Purpose:

• Instead of having the tables with the raw hex fly by on your terminal you can now use the --raw or --rawest option to simply print the raw data coming over serial as a hex string. This helps greatly with debugging firmware issues because it shows how your data is packed and helps with identifying patterns in data.
• From the README.md:
  

Changes:

• Added --raw option to the argument list and its associated print hex statement. This option is meant to print the message field that will be sent to the parser.
  

• Added the --rawest option to the argument list and its associated print hex statement. This option prints the exact hex chunk received over radio without any post-processing with the process_message function (this just cuts up the chunk into valid message pieces).
  

• Added try and catch check for fromhex error when converting hex message to latin-1 string in process_message function. This previously would crash the problem (the reason for this problem existing it unknown), now it will print what it tried to convert and will DISCARD THE ENTIRE CHUNK COLLECTED.

• Added README.md for the memorator upload script so people know to change the log folder path to where the SD card is before uploading.

FIXES:

• Previous fix_concat_msg branch missed changing parse_response['message'] to msg in the no-write endpoint on the parser. This meant that any concatenated messages would not be split up and parse fails would still occur.
• Variable fail_msg accessed in the INFLUX_WRITE_FAIL check, however, was only initialized in the PARSE_FAIL check outside of scope.
• This emphasizes the important of running all types of tests rather than low-message-rate tests where no stress is applied. A test suite will automate this but the underlying issue of missing tests is crucial.

I think it would be good to make it very clear that the args.rawest prints can have incomplete messages. Can you please add their usage (as well as this warning) in the README
