TODO:
* nk2export check if always adding .export is the desired behavior
* libnk2_io_handle.c check if LIBNK2_VALUE_TYPE_BOOLEAN is working as intended
* item values
  - implement currency as: LIBFVALUE_VALUE_TYPE_FIXED_POINT_64BIT
    what about location of the point ?
* in io_handle_read_items used set array value instead of append ?

Optimizations:
* map (file offset and size) items and item values first read on demand ?
* pre allocate item array entries

library
* additional value type support functions
  - filetime
* what about multiple alias entries 0x6001 of a single item?
  - they are set in values table but identifier lookup will return first only
* local library support

Tools
* add signal handling
* nk2export
  - add export mode like pffexport
  - export alias files instead of item values
  - export to CSV/TSV, HTML, XML
  - add -d option to dump item values and use this in test_nk2export.sh
* nk2info

Beta release
* remove deprecated definition in include/libnk2/mapi.h
