Python ASN.1 benchmarks

Benchmarks for the same ASN.1 structures encoded/decoded with cryptography, pyasn1, and asn1crypto.

The benchmark covers:

• a small RSA private key sequence
• a Doohickies sequence with primitive fields, object identifiers, and a set of generalized times

The decode benchmarks are named decode_access_one_field because the timed function decodes the DER input and accesses one child field. This is intentional: asn1crypto lazily loads child fields, so timing only load() would measure construction of the lazy wrapper rather than comparable field access.

The asn1crypto encode benchmark uses normal cached dump(), not dump(force=True).
