Add SchemaInferenceOptions options to infer_schema and option to configure int96 inference

[jaychia]

This PR addresses part 2 of #1527

It solves the problem of configuring arrow2's Parquet schema inference to infer Timestamp fields from Parquet Int96 fields differently based on user input.

1. Adds a new SchemaInferenceOptions struct which allows for configurability of how schema inference on Parquet files
2. Adds a int96_coerce_to_timeunit flag to configure how Parquet int96 fields are inferred as arrow Timestamps
3. Adds *_with_options variants of the infer_schema and parquet_to_arrow_schema APIs to take in the options

Hi @ritchie46 and @sundy-li

Here's a follow-up PR to https://github.com/jorgecarleitao/arrow2/pull/1532

(see PR description for more details)

[sundy-li]

BTW, int96 seems to be deprecated in parquet, it's not a stable feature. https://[issues.apache.org/jira/browse/PARQUET-323](https://issues.apache.org/jira/browse/PARQUET-323)

Indeed, but it is still widely used and supported by many systems for backwards-compatibility reasons

Unfortunately because Parquet is a long-lived format, and many enterprises use old versions of data frameworks, these deprecated features tend to live long after their deprecation :)
