Current ctx seems to be broken for the simulator. This is an older
release, which doesn't have our newest fonts, but at least it kinda
works.

This update brings some fixes to excluding miniz from build and
enabling binary search for glyphs in the internal font engine.

Also make licensing clearer, ctx.h itself which is in this folder is
licensed under LGPLv3+, it is the micropython bindings - uctx which
live in ../micropython/usermodule/mp_uctx.c which are MIT licensed.

Short reads generally shouldn't happen, but let's be defensive there.

Instead, let's explicitly check the return code of i2s reads.

Brought to you by: “my interrupt didn't get initialized and i got very
confused”.

1. The page preview seems unusable anyway, as GitLab doesn't serve HTML
   pages (only allows to download them).
2. Rules seems broken and 'splits' pipelines:

   In return, 'only' is deprecated, but at least it works.

This also hopefully stops us from submitting random MR docs onto the
production pages.

We need to have the bmi270 component available, even though we don't
even link against it.

This moves the raw read/write access code from the recovery mode into
st3m, and gives us the ability to mount/unmount the FAT partition on
demand.

This should make it easier to run clang-check/clang-tidy locally.

Only ctx.arc has a 6th integer argument, integer truncation was applied to
all 6-argument methods.

Tested by doing the following in REPL:

    >>> import hardware
    >>> ctx = hardware.get_ctx()
    >>> ctx.rgb(1, 0, 0)
    <ctx_type>
    >>> ctx.rectangle(-120, -120, 240, 240)
    <ctx_type>
    >>> ctx.fill()
    <ctx_type>
    >>> hardware.display_update(ctx)

Fixes #25.

Whoops.
