v2.7.2
Changes:
- Improve behaviour of cache reader in the face of underlying IO errors.
- if the start of the requested content from a cache reader is available, then present that, and just stop where the IO error occurrs, rather than erroring the entire "read()"
- "--args" now indirects through references and pointers when printing function arguments
- Clean up ReaderArray and its iterators to be more conformant to C++ iterator concept
- Fix a bug in the --dump options that faulted due to previous FDE parsing optimisations.
