[Library Manager] Please add ThinSat Program TSLPB Library

[nickcounts]

Hello Arduino team,

Please add:
https://github.com/VCSFA-MARS/TSLPB

to the library manager. This is a library for participants in the ThinSat program to help use the Student Payload Board, and to facilitate transmission of data to the NSL MotherShip.

Thank you!
