Pin the SHTC3_v2 dependency to an immutable commit.

The new external usermod tracks the repository’s moving default branch, so future builds may silently consume different code. Pin it to a commit SHA, consistent with the nearby audioreactive dependency.

Updated waveshare_esp32s3_32MB_hub75 build env to include SHTC3 UM, enabling the onboard temp/hum sensor.

[softhack007]

@lost-hope is this an "official" usermod?

[Will-wastelander]

@softhack007 They created this UM at my request, in #sensors on discord. I'm not sure if they have released it to WLED-AC yet or not, but I wanted to get this added to the build env, so it would have the support. Here is the link to their post in that channel.

[softhack007]

@lost-hope I've quickly looked through the UM code.

One line is a bit problematic

https://github.com/lost-hope/SHTC3_v2/blob/b8a648e7b71ac1bb6efca1bacdf6577aeb17b09c/SHTC3_v2.cpp#L134

this delay() runs in the main loop, it can lead to effect stuttering for higher framerates, especially above 60FPS.
