TurboJPEG: Improve error handling

Browse Source 
- Provide a new C API function and TJException method that allows
  calling programs to query the severity of a compression/decompression/
  transform error.
- Provide a new flag that instructs the library to immediately stop
  compressing/decompressing/transforming if a warning is encountered.

Fixes #151
