Field sqrt optimization (#168)
* add more Fp tests for Twisted Edwards curves

* add fused sqrt+division bench

* Significant fused sqrt+division improvement for any prime field over algorithm described in  "High-Speed High-Security Signature", Bernstein et al, p15 "Fast decompression", https://ed25519.cr.yp.to/ed25519-20110705.pdf

* Activate secp256k1 field benches + spring renaming of field multiplication

* addition chains for inversion and sqrt of Curve25519

* Make isSquare use addition chains

* add double-prec mul/square bench for <256-bit prime fields.
