**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] (This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*) --> Currently a `ParquetFileArrowReader` is created from a `ChunkReader` or an `Arc<dyn FileReader>`, and an optional set of `ArrowReaderOptions`. Then `ArrowReader` can be used to obtain a `ParquetRecordBatchReader` from this. Not only is this interface deeply confusing, but it is unclear how to extend it to support functionality such as row filtering, predicate pushdown, etc... which needs the schema information before it can be computed, information which is only available after the file has been opened. **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> I would like a `ParquetRecordBatchReaderBuilder` similar to `ParquetRecordBatchStreamBuilder` **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
