Investigate release binary size about grimoire-legacy

[jshrake]

TLDR: I can bring the size of the release binary down to ~3.4 MiB by running strip, and following the advice in https://github.com/johnthagen/min-sized-rust.

Without doing anything, a release build weighs in at 4.6 MiB:

58.0% 100.0%   2.7MiB .text section size, the file size is 4.6MiB

After running strip, 3.8 MiB:

~/code/grimoire 15s
❯ strip target/release/grimoire

~/code/grimoire
❯ ls -lh target/release/grimoire
-rwxr-xr-x  1 justin  staff   3.8M Mar 31 20:02 target/release/grimoire

Following the suggestions in https://github.com/johnthagen/min-sized-rust, I can bring the size down to ~3.4 MiB.

Random thought: could we somehow use grimoire to emit an artifact that contains the exact set of GL calls + shader code required to render? code generation seems scary and out of scope for this project, but I highly doubt that we'll ever be able to shrink grimoire down to a suitable size for a 64k entry.
