Which issue does this PR close?

error[E0282]: type annotations needed
   --> .cargo/registry/src/index.crates.io-1949cf8c6b5b557f/parquet-54.3.0/src/arrow/schema/primitive.rs:117:49
    |
117 |     if precision <= DECIMAL128_MAX_PRECISION as _ {
    |                                                 ^ cannot infer type

For more information about this error, try `rustc --explain E0282`.
error: could not compile `parquet` (lib) due to 1 previous error

Rationale for this change

I'm not sure why rustc fails to infer the type here. This showed up after updating parquet to 0.54.3 (as a dependency of a different crate).

What changes are included in this PR?

Add type annotation.

Are there any user-facing changes?

No.
