Other way to construct towered extension fields #203

Is it possible to construct towered extension fields in another way? For example, fp12 now is constructed from 1-2-6 -12, but fp12 can also be constructed from 1-2-4-12. So, is there any reason why the extension fields are constructed the currrent way? And is it possible to support other towered extension filelds?

The current fields are constructed such that the fastest formulas for multiplication/squaring are obtained. If you look at squarings, you will see that we switch from 1-2-6-12 to 1-2-4-12 for efficiency.

tarakby pushed a commit to onflow/crypto that referenced this issue Dec 8, 2023
The diff contains:
- a lot of changes that concern parts of the library we don't use (other curves a la BN, BLS24-X, BLS12-383 ...), integer protocols (ETRS), field extension machinery ...
- otherwise irrelevant changes, e.g. CI/CD
- some memory bug fixing
