📄 Description

Adds the initial skeleton of HLE libSceJpegEnc. Functions except encode are fully implemented, encode has some of the validity checks but is otherwise stubbed.

Tested in CUSA06093 with the PV screenshot functionality. Obviously no actual JPEG is encoded but the encoder is set up correctly and passes the validation checks.
