Library:
--------
- Added support for in-place type conversion in most cases
In-place type conversion allows the library to perform type conversion
without an intermediate type conversion buffer. This can improve
performance by allowing I/O in a single operation over the entire
selection instead of being limited by the size of the intermediate buffer.
Implemented for I/O on contiguous and chunked datasets when the selection
is contiguous in memory and when the memory datatype is not smaller than

- Changed selection I/O to be on by default when using the MPIO file driver
