Rename phasorinc, add {C,D}Collection documentation, and main() → main.cpp

[samcunliffe]

There was a hanging documentation and a renaming task from our last meeting with Peter.

I also include a few minor sanity fixes:

• I moved main into main.cpp.
• Fixed the broken <details> tags (or at least it's fixed with my local doxygen version).
• Updated the version of doxygen (I hope).

On the deployed version we have...

Looks good 👍

Although I noticed that the current README usage instructions are also somewhat out of date (they don't mention the -h, -m or -fd flags, for example).

Maybe we should look to update this file? Or we could hold off till hdf5 has replaced MATLAB.

Good point, let's fix that here too whilst I'm in a documentationey mood. (It's better to have the documentation change along with changes to the code. ... Implying the doc was there beforehand 😹 )

Looks OK, although has the -fd option disappeared? It's no longer in the documentation you've written. If it's deliberate ignore my other comments.

It looks like the tdms_tests executable is failing to build too since the GLOB update - I can't see anything wrong with the CMakeLists file though, so maybe there's something in targets.cmake that needs updating?

Tests fail because I (stupidly) didn't check the tests target. And this regex also finds main.cpp so there's a clash between the catch2 main() and the tdms main().
