Add support for translating numeric/binary values

- SYSCALL: arch, syscall
- everywhere except EXECVE, PROCTITLE: *uid, *gid
  - *uid, *gid fields get special treatment in the parsing stage
    because they occur so frequently.
- SOCKADDR: saddr

A Key variant for translated values that are serialized in UPPERCASE
is added.

The result is mostly comparable to auditd does when configured with
log_format=ENRICHED.
