Feat: added support for the SHT3x sensor

[Tomas-Kuchta-FPV]

Hi, this is my first contribution to the MeshCore repo.
This code has been partially helped using copilot and I don't understand everything that much so please be thorough with the review.

Changes

• Implemented SHT3x library.
• Implemented a simple check for INA226 as it's on the same addres

Testing

Everything was tested on Heltec V3 and it seems to work. Everything shows up as it should.
