Renamed adaptive_he to adaptive_histogram_equalization

[Paul92]

Description

On develop, tests were failing because of missing adaptive_he.cpp, which was renamed to adaptive_histogram_equalization.cpp.
Since adaptive_histogram_equalization seems more consistent, I took the liberty to modify all the occurences of adaptive_he to `adaptive_histogram_equalization.

Thanks for the PR. You changed the source file name in jamfile but forgot to change the name of the actual file :)

Thanks for your comment. It's either me being confused or not making myself clear, but the problem was that the tests weren't working since adaptive_histogram_equalization.cpp was already renamed (hence the tests not working) - I just renamed the rest.

Maybe the confusion comes from the fact that this MR also renames the documentation .md file for consistency (which is fine).

[sdebionne]

I believe the failing pipelines have nothing to do with the changes introduced in this PR:

testing.capture-output bin.v2/libs/gil/test/extension/io/simple_all_formats.test/gcc-8/release/cxxstd-2a-iso/threading-multi/visibility-hidden/simple_all_formats.run
====== BEGIN OUTPUT ======
Segmentation fault (core dumped)

EXIT STATUS: 139
====== END OUTPUT ======

The runners are probably running out of memory (or cxxstd-2a-iso is buggy in GCC8).

@sdebionne Yes, I think this can be merged.

It's shame the CI is still broken, but my work here mloskot#3 is still being kind of blocked by boostorg/filesystem#226 aka boostorg/cmake#17

Although with this #636 merged, it should be easier to work around it. I'll pick the task this week yet.

Thanks. I'm going to merge this.

If it causes any CI failures, then I'll take care of them.
