Add MIT licence

Declared with the PEP 639 license / license-files fields, so the text ships in
the wheel and the image rather than only the repository. Records the terms of
the two things this repository deliberately does not contain: Boxsim, which is
Visaton freeware and is never redistributed, and kicad-visaton-lib, which is
CC-BY-SA-4.0 and is copied into any image built by tools/build-image.sh.

Verified: pip install exposes License-Expression MIT and packages the text as
dist-info/licenses/LICENSE, both on the host and in the image.

+Two things this repository deliberately does not contain, and their terms if you assemble them yourself:
+
+- `Boxsim.exe` and the Boxsim distribution are Visaton freeware. Only the development-only oracle touches the binary, and no part of it is redistributed here or in the image.
+- [kicad-visaton-lib](https://src.bundespruefstelle.ch/magdev/kicad-visaton-lib) is CC-BY-SA-4.0. `tools/build-image.sh` copies it into the image it builds, so an image you publish carries that licence alongside this one.
