A good portion of the values that one would want to be examine with
scylla-tools will be partition or clustering keys. While examining them
was possible before too, especially for single component keys, it
required manually extracting the components from it, so they can be
individually examined.
This series adds support for working with keys directly, by adding
prefixable and full compound type support.
When passing --prefix-compound or --full-compound, multiple types can be
passed, which will form the compound type.
Example:
$ scylla_types --print --prefix-compound -t TimeUUIDType -t Int32Type 0010d00819896f6b11ea00000000001c571b000400000010
(d0081989-6f6b-11ea-0000-0000001c571b, 16)
Another feature added in this series is validation. For this,
`compound_type::validate()` had to be implemented first. We already use
this in our code, but currently has a no-op body.
Example:
$ scylla-types --validate --full-compound -t TimeUUIDType -t Int32Type 0010d00819896f6b11ea00000000001c571b0004000000
