sm64ex-coop builder Termux v0.1.2

I have created this auto builder to expand access to sm64ex-coop for Android. This is intended to be compatible with both Termux official mirrors and my version of sm64ex-coop for as long as possible, but it will inevitably eventually stop working. I might or might not create future updates to this. I don't believe semver is objectively appropriate for my project, but Termux's github workflow steers me towards it and it might satisfy someone who thinks everything in existence should have semver, so I've used it for convenience.
