Which issue does this PR close?

Rationale for this change

The parquet::format module is no longer needed, but because it has been part of the public API it should go through the normal deprecation process.

What changes are included in this PR?

In addition to the deprecation notice, this modifies the documentation for the parquet-layout binary which relies on the format module to read page headers. This tool will be removed when format is removed.

Are these changes tested?

None needed.

Are there any user-facing changes?

Yes, public module is marked as deprecated. Not a breaking change, however.
