*added version info and build time info

[AMV007]

added vscode settings to exclude max_payload_size to more clear size

couple points:

• this is all good improvements
• most of the commiters here are used to the linux kernel way of structuring changes (one change per commit), but that's not a big deal for me with such small patches
• qdl (lowercase) seems to be the used throughout the codebase
• I think having a git hash in the print would be very useful (say qdl version 1.0.0-1234abde)
• the date could use a LC_ALL=C in the front
• since i added so many nits, I may as well ask to put a space between the * and the operands in the max_payload_size declaration :wink:

thanks!
