fix multiple regexes, add more hiders, add uhc overlay

[MicrocontrollersDev]

Description

• fix multiple regexes. these haven't been tested since actually triggering these is time consuming and I don't want to wait tbh
• add gexp hider, also not tested
• add time played remover, also not tested
• add uhc overlay, tested in a singleplayer superflat but unless I messed up the locraw or hypixel check somehow it should be good. max allowed value might be up for debate, and I'm also not sure I followed the style properly

(note: the regexes have not yet been added to datastorage as they have not been tested)
