This adds a pure-Go ed25519 BatchVerifier implementation based on the ed25519consensus library, with additional checks to preserve our ed25519 validation criteria, last updated in #3031. Like our libsodium batch verification implementation, the IsCanonicalY check here is also based on the "Taming the Many EdDSAs" paper in https://eprint.iacr.org/2020/1244 New tests added to compare ed25519 criteria results match our existing libsodium- and ed25519-donna-based batch verification implementation (from #3031 and defined in algorandfoundation/specs#60). New test helpers run test vectors with different batch sizes, taken from - 12 edge cases from "Taming the many EdDSAs" Appendix C, Table 6c, also used in our libsodium fork's tests in batch verification: add ed25519 batch verification implementation #3031 - 1025 successful cases from our libsodium fork's tests, also added in batch verification: add ed25519 batch verification implementation #3031. - 196 edge cases used to draw the 14x14 grid visualizations from the blog post "It's 255:19AM. Do you know what your validation criteria are?" and used in ed25519consensus - 768 edge cases from the Go crypto package's crypto/ed25519/ed25519vectors_test.go
