Ant script added for building Java JPMS module for Mem Ops

This release only adds an Ant for building Java JPMS module for Mem Ops. No other functional changes.

Minor fix of Bytes.allocate()

Bytes.allocate() now sets all indexes in the Bytes object correctly. Before, endIndex, writeIndex and readIndex were not set properly by allocate(). They are now.

0.6.2 Bytes + BytesFactory updates

The Bytes + BytesFactory have been updated to use an IBytesAllocator (interface) instead of a BytesAllocatorAutoDefrag which they used before. Today Mem Ops has 2 IBytesAllocator implementations, BytesAllocatorAutoDefrag and BytesAllocatorManualDefrag. Bytes and BytesFactory should be able to work with both of them!

0.5.1 First Release

This the first release of Mem Ops for Java
This version contains the basic byte and object allocation functionality.
More advanced functionality will follow in later versions.
This version uses Java 8. Later versions will move to Java 11.
