### Rationale for this change
There is currently an active proposal to support half-float types in
Parquet. For more details/discussion, see the links in this PR's accompanying
issue.
### What changes are included in this PR?
This PR implements basic support for a `Float16LogicalType` in accordance
with the proposed spec. More specifically, this includes:
- Changes to `parquet.thrift` and regenerated `parqet_types` files
- Basic `LoticalType` class definition, method impls, and enums
- Support for specialized comparisons and column statistics
In the interest of scope, this PR does not currently deal with arrow
integration and byte split encoding - although we will want both of these
things before the proposal is approved.
### Are these changes tested?
Yes (tests are included)
### Are there any user-facing changes?
Yes
