Compiling ToastStunt on tilde.town

This was done quite haphazardly, please excuse my vague documentation.

The process mostly followed the build instructions in the toaststunt readme. Tilde-specific tweaks below:

Had to patch the code due to trixie not shipping pcre3 - See git diff
Requires gperf binary to calculate hashes.
- To avoid having to install stuff on tilde.town, I took this out of the trixie docker container and scp'd it up, lol
- After running cmake ../, it failed to find gperf. I am too st00pid to fix it properly so I just edited the generated CMakeCache.txt to have gperf_EXECUTABLE:FILEPATH=/home/rbiv/toast/gperf
