oss-detect-cryptography does not support sarif

Something in the command line parser for oss-detect-cryptography is broken:

PS C:\dev\source\github\OSSGadget\src\oss-detect-cryptography\bin\Debug\net6.0> .\oss-detect-cryptography.exe --format sarifv2 --output-file foo pkg:npm/left-pad@1.3.0

WARN  - --format was neither a Package URL, directory, nor a file.
WARN  - sarifv2 was neither a Package URL, directory, nor a file.
WARN  - --output-file was neither a Package URL, directory, nor a file.
WARN  - foo was neither a Package URL, directory, nor a file.

Start with the oss-detect-cryptography command-line entry point and reproduce the documented PowerShell command using --format sarifv2 and --output-file foo. Trace how these arguments are parsed versus package inputs; done means the flags are accepted and the command no longer warns that them or their values are packages.
