* Added `CodecOptions` struct to hold `Codec` configuration.
* Added `backward_compatible_lz4` option in `CodecOptions`.
* Added `CodecOptions` to `ReadOptions` to be able to configure `SerializedFileReader`.
* Added `SerializedRowGroupReaderOptionsBuilder` with `CodecOptions` to be able to configure `SerializedRowGroupReader`, with extensible interface.
* Added `SerializedPageReaderOptionsBuilder` with `CodecOptions` to be able to configure `SerializedPageReader`, with extensible interface.
* Added `new_with_config` to `SerializedPageReader` API to be able to configure `SerializedFileReader` without breaking `new` API.
* `CodecOptions` implements `CopyTrait` as it is composed by `Copy` types. If in the future it contains a non `Copy` type, maybe is better to create `CodecOptionsPtr = Arc<CodecOptions>`.
* `CodecOptions` is only added in the read path, in the write path the default values are taken, as the options currently only affect the read path and have no effect on write path. If required to add to write path maybe it will be nice to add into `WriteProperties`.

* Added compression and decompression for LZ4_HADOOP.

* Added a test for two parquet files with the same content, both with LZ4 CompressionCodec, but one using the LZ4_HADOOP (no-fallback) algorithm and the other LZ4_RAW algorithm (fallback to last level).
* Refactor `LZ4HadoopCodec::compress` function to make it easier to understand.

This commits hides `CodecOptions` from the public API. The changes are the following:
- Added a new structs to public API `ReaderProperties`, `ReaderPropertiesBuilder` and `ReaderPropertiesPtr` to store inmutable reader config, as it is the case of `CodecOptions`.
- Removed `SerializedRowGroupReaderOptions`, `SerializedRowGroupReaderOptionsBuilder`, `SerializedPageReaderOptionsBuilder` and `SerializedPageReaderOptions`. They are not required anymore as `SerializedRowGroupReader` and `SerializedRowGroupReaderOptions` use `ReaderPropertiesPtr` for configuration.
- `SerializedRowGroupReader::new_with_options` renamed to `SerializedRowGroupReader::new_with_properties`.
- `SerializedPageReader::new_with_options` renamed to `SerializedPageReader::new_with_properties`.
- Test added for `ReaderPropertiesBuilder`.
