Document location of binary blob files

[kubark42]

It seems that a recurring question from users is where to find the binary blobs. This is possibly being driven by the fact that the README.md doesn't make mention of these, and instead instructs new users to compile the firmware via make.

An excellent resource was just created at https://github.com/lbuque/lilygo-micropython/actions/workflows/nightly-build.yml, and it might help to avoid this user confusion if this were mentioned as the primary installation path, and perhaps included in the releases.

I have to flash to 0 instead of 0x1000 but it does "seem" to be working. Not many (none) examples for Micropython so trying to find some more to test on. Ok, yes I have most of it working now, just have to start at 0 for some reason? Thanks!
