* Updated sig templates to add support for arch specific upstreams. Currently behaves as expected, but still need to test (and integrate) dilithium * Fixed a couple of build errors, and started work on dilithium integration from pqclean. Currently failing kat tests * Updated templating for both sig and kem to make them look a little better * Renamed dilithium folders so they are consistent across pqclean and pqcrystals so that copy_from_upstream script will function correctly * Added arm optimized version of dilithium[2|3|5] * Updating other signature schemes CMakeLists.txt to be the output of the updated templates * Arm optimized implementation of dilithium is added, with randomized signing patched into it. copy_from_upstream script is working properly. Still need to update the update_docs scripts before ready to merge * Finished updating docs scripts and yml files. Builds pass, so should be ready for a merge * Fixed template issue with multiple compile flags * Updated doc generation scripts so that all '_' in scheme names are replaced with '\_'
