Update gsl-lite to 1.0.1

[musicinmybrain]

See https://github.com/gsl-lite/gsl-lite/releases/tag/v1.0.0 and https://gsl-lite.github.io/gsl-lite/#migration-guide.

In gsl-lite 1.x, gsl_CONFIG_ALLOWS_SPAN_COMPARISON defaults to 0, so I implemented it manually for morphio::range.

Hello---any updates here please? (If it isn't an issue, the gsl git submodule should also be updated to v1.x---v0.4 is 5 years old..)

Sorry, I haven't had much time for maintenance on this repo; I will see if I can find time.

@sanjayankur31 > no hurry as always

I looked at this a bit yesterday, and it seems that upstream has changed how they have laid out their CMake files.

I'm considering "just" versioning in the gsl-lite requirement, but I don't know what the impact on packaging would be in that case. Do you have any guidance @sanjayankur31?

[sanjayankur31]

Do you mean pinning it to a particular version? In that case, if this version is not what the Fedora package of gsl-lite is at, we'll need to bundle that in when we build morphio, but that's fine for us to do.

It will likely mean that morphio will remain pinned on an older version of gsl-lite, since no one will be testing it with newer versions. We can try it out with the gsl-lite package from time to time downstream and provide feedback. For this ticket, I guess if morphio is pinned to gsl-lite v1.x now, that should work for a long time (assuming that gsl-lite follows semver and remains API compatible throughout the v1 series).
