In an effort to clean-up and standardize UPM library
documentation, this commit updates (and in most cases,
unifies) the CMake description string AND CXX header
@comname string.
Strings were taken from datasheets when possible, spelling
mistakes were addressed, copy/paste errors where fixed,
Title Case was used, etc.
* Tested/updated/added @web tags
* Added/updated invalid sensor images
* Added/updated @man tags, added missing manufacturers
