* Check that the cache working directory is clean
* cpm_check_working_dir_is_clean for non git repo will not terminate cmake
* sileneced check for git repo, in case of error
* style(CPM.cmake): fixed indentation for ERROR_QUIET
* refactor(CPM.cmake): added logic to handle a cache folder inside a (not correlated) git repo
this is accomplished by checking if we are in the directory where .git lives
* style(CPM.cmake): stray tab to spaces
* test(dirty-cache-check): added unit test to check cpm_check_working_dir_is_clean
the test creates a file in a folder and then uses git to create a repo in that folder, to check various conditions
* Update test/unit/dirty-cache-check.cmake
added user.name and user.email to comply with test machine where git is not completely configured

* feat(cpm_check_working_dir_is_clean): now it takes a git tag (works with hashes too) to check for uncommitted and commited changes
* refactor(cpm_check_working_dir_is_clean): early return for the most common case of uncommited changes in a repo
* refactor(cpm_check_git_working_dir_is_clean): removed edgecase detection (a non-git folder in an unrelated git repo)
now the contract is that com_check_git_working_dir_is_clean is given the base folder of a git repo
