iccSpecSepToTiff needs command line help output similar to other Tools.

Sample Tool Outputs

iccSpecSepToTiff

Usage: SpecSep2Tiff output_file compress_flag sep_flag infile_fmt_file start_nm end_nm inc_nm [embedded_icc_profile_file]

iccDumpProfile

Usage: iccDumpProfile {-v} {int} profile {tagId to dump/"ALL"}
Built with IccProfLib version 2.3.1.1

The -v option causes profile validation to be performed.
The optional integer parameter specifies verboseness of output (1-100, default=100).
iccDumpProfile built with IccProfLib version 2.3.1.1

iccToXml

IccToXml built with IccProfLib Version 2.3.1.1, IccLibXML Version 2.3.1.1

Usage: IccToXml src_icc_profile dest_xml_file

iccApplyProfiles

iccApplyProfiles built with IccProfLib version 2.3.1.1

Usage: iccApplyProfiles src_tiff_file dst_tiff_file dst_sample_encoding dst_compression dst_planar dst_embed_icc interpolation {{-ENV:sig value} profile_file_path rendering_intent {-PCC connection_conditions_path}}

For dst_sample_encoding:
0 - Same as src
1 - icEncode8Bit
2 - icEncode16Bit
4 - icEncodeFloat

For dst_compression:
0 - No compression
1 - LZW compression

For dst_planar:
0 - Contig
1 - Separation

For dst_embed_icc:
0 - Do not Embed
1 - Embed Last ICC

For interpolation:
0 - Linear
1 - Tetrahedral

For rendering_intent:
0 - Perceptual
1 - Relative
2 - Saturation
3 - Absolute
10 - Perceptual without D2Bx/B2Dx
11 - Relative without D2Bx/B2Dx
12 - Saturation without D2Bx/B2Dx
13 - Absolute without D2Bx/B2Dx
20 - Preview Perceptual
21 - Preview Relative
22 - Preview Saturation
23 - Preview Absolute
30 - Gamut
33 - Gamut Absolute
40 - Perceptual with BPC
41 - Relative Colorimetric with BPC
42 - Saturation with BPC
50 - BDRF Parameters
60 - BDRF Direct
70 - BDRF MCS Parameters
80 - MCS connection
+1000 - Use Luminance based PCS adjustment
+10000 - Use V5 sub-profile if present

Do we have any tests that actually use iccSpecSepToTiff ?
This had a few unsafe bits, and potential problems based on parameters chosen.

What I currently have:

Usage: iccSpecSepToTiff output compress sep infile_fmt start end incr {profile}
Concatenates several spectral TIFF files into a single file, with optional embedded ICC profile.
	output: path/name of the TIFF file to be created
	compress: boolean (0 | 1), should the output be compressed
	sep: boolean (0 | 1), plane data be seperated in the output TIFF
	infile_fmt: printf format string for input files, example: "spec_%06d.tiff"
	start: integer, first channel number to process
	end: integer, last channel number to process
	increment: integer, increment between channels
	profile: optional ICC profile to embed in the output TIFF

None known but will work on corpus following your PR.

Thank You!!
