Subject: public_key: Remove legacy switch compact_bit_string
* E.I bitstrings will not be decode as {Unused, Binary}, they are now
Erlang bitstrings.
* Also the compact_bit_string implies the legacy_erlang_types switch
- So removing the switch will also make OCTET STRING values be represented
as binaries.
- Undecoded open type will now be wrapped in a asn1_OPENTYPE tuple.
We need to handle this in pubkey_pbe.erl, maybe this can be eliminated
later by updating/refreshing ASN1-specs.
This will change some values in records returned by the public_key API
making this change a potentiall incompatibility.
