[table flipping] Rewrite everything in Rust - keep the name though

[blefaudeux]

Looks like some stability issues cannot be completely nailed, stack too big and not everything is in scope. The current end to end stack covers
python, go (interfaced with gopy) and C for some lower level libraries (like libvips)

Salient issues are that

• speed is lower from the python side post golang 1.18, hard to address without diving deep in gopy
• govips doesn´t expose the whole libvips interface, and while all vips calls can error out and these are caught, vips can hard crash on some images when trying long enough

It is possible to remove the libvips dependency and stick to pure Go on the image processing side, but we become CPU bound in this case.

Moving to Rust -and sticking to Rust native code- could remove one layer in this stack (no more C give or take), and benefit from more compile time guarantees

a proof of concept is on the ben/rust branch, running already without the python integration, currently bulletproofing an initial skeletton

proof of concept running in Rust, doing 70% of the existing go code, looks like it's a more reasonable future
