feat(robot): environment variable for load library timeout

[Noordsestern]

Closes #505

Environment variables don't seem to be documented, hence I did not start documenting.

Also renamed the other constants in the file (TIMEOUT instead of TIME_OUT).

Details:

Configure LOAD_LIBRARY_TIMEOUT with environment variable ROBOTCODE_LOAD_LIBRARY_TIMEOUT

Sorry—I know you’ve already put a lot of work into it. But depending on how you want to submit it—either as a single patch or as individual commits—you should follow the Contributing Guide, sign your commits, and adhere to the Conventional Commits rules. If you want to leave it as is, I can only create a patch and apply it; you’ll of course be credited as a co-author, but then it won’t be clear which parts of the code you wrote.
