Inconsistency between CLI help and implementation for COPC support in translate

[mone27]

The help of the translate command says that the output-format can be las, laz or copc

wrench/src/translate.cpp

Line 37 in f8d5dae

argOutputFormat = &programArgs.add("output-format", "Output format (las/laz/copc)", outputFormat);

However in the implementation it rejects copc arguments

wrench/src/translate.cpp

Lines 56 to 60 in f8d5dae

	if (outputFormat != "las" && outputFormat != "laz")
	{
	std::cerr << "unknown output format: " << outputFormat << std::endl;
	return false;
	}
