feat(process): Pull the database at runtime

[Covkie]

This is preferred as it allows users to always have the latest db without worry & enables embedded arrpc to have the latest db without recompiling; see Vesktop or Legcord

Currently fetches if the database is 24 hours old but maybe check the headers at https://discord.com/api/v9/applications/detectable to see if it is ACTUALLY out of date

Do you know if this would work fine even when arrpc is bundled and/or in an asar file?

from the Vesktop PR: https://github.com/Vencord/Vesktop/blob/cb342c8c6875dee20937c99ffbf2414d251d4eba/patches/arrpc%403.5.0.patch

@CanadaHonk A patch would still be needed for proper location stuff but yes it does work.
Maybe when initializing arrpc you should pass the path then. Would remove the need for patches like this.

Also, Vee told me discord has an endpoint for fetching deltas so maybe the latency on fetching updates can be improved here. I haven't looked into it though. Nvm vee is a liar

When fetching /applications/detectable, the response headers include the Last-Modified header

We can include the time here in our GET with the If-Modified-Since header to only fetch the database if it has changed since. If it hasn't changed, Discord will send a 304 Not Modified
