c81e91e8ca TurboJPEG: New flag for limiting prog JPEG scans 
This also fixes timeouts reported by OSS-Fuzz.

dc4b900223 TurboJPEG: Add alpha offset array/method 
Also, set the red/green/blue offsets for TJPF_GRAY to -1 rather than 0.
It was undefined behavior for an application to use those arrays/methods
with TJPF_GRAY anyhow, and this makes it easier for applications to
programmatically detect whether a given pixel format has red, green, and
blue components.

dadebcd79a TurboJPEG: Add "copy none", progressive xform opts 
Allow progressive entropy coding to be enabled on a
transform-by-transform basis, and implement a new transform option for
disabling the copying of markers.

Closes #153

aba6ae5950 TurboJPEG: Opt. enable progressive entropy coding 
Fulfills part of the feature request in #153.  Also paves the way for
SIMD-accelerated progressive Huffman coding (refer to #46.)

d4092f6b4d TurboJPEG: Improve error handling 
- 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

fac3bea8da Add a Java version of TJBench and extend the TurboJPEG Java API to support it (this involved adding a polymorphic method in TJCompressor that accepts x and y offsets into a larger buffer, similar to the previous modification that had been done to TJDecompressor.)

b2f9415a63 Slight refactor to put ScalingFactor into its own class (mainly because the $ in the class name was wreaking havoc on the build scripts, but also to add a few convenience methods to it) and to create a separate loader class so we can provide a .jar file with the MinGW distribution that loads the correct DLL
