* 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 '\_'
* Point Kyber and Dilithium to pqcrystals-repo.
* Pulls Kyber and Dilithium from PQCrystals using copy_from_upstream
* Dilithium Round 3
* Kyber round 3
