Currently, a ParquetRecordBatchReader would has a plan for read. It's
maximum read row count is a fixed-sized number, can we try to expose this?
**Describe the solution you'd like**
Add a `row_count` interface for it, would be like ( the impl is incomplete )
```rust
pub(crate) fn remaining_row_count(&self) -> usize {
match &self.selection {
None => 0,
Some(s) => {
let mut value = 0;
for v in s {
if !v.skip {
value += v.row_count;
}
}
value
}
}
}
```
**Describe alternatives you've considered**
Any row-count like interface is ok
**Additional context**
No here
