Minor documentation fixes (#890)

Some minor documentation fixes:

- Wrong link, `isCubemap` should be `isCompressed`:
7a45c4e615/include/ktx.h (L329)
- Unnecessary `n` at
7a45c4e615/include/ktx.h (L341)
- Typo: "betweeb" should be "between" at
7a45c4e615/lib/texture.c (L831)
- Unnecessary `<` at
7a45c4e615/tools/ktx/command_create.cpp (L765)
- The link to pyktx is missing `../` in
7a45c4e615/pkgdoc/toolsDoxyLayout.xml (L41)
and related files (I.e. on
https://github.khronos.org/KTX-Software/libktx/index.html , the link to
pyktx is a 404), see
https://github.com/search?q=repo%3AKhronosGroup%2FKTX-Software%20%22pyktx%20Reference%22&type=code
