add RESOURCE_LOCATIONS==module (for resmgr CLI)

[bertsky]

Another glitch that went under the radar. It must be possible to choose ocrd resmgr download -l module (even if module may already be the default, but it should at least appear as a CLI option).

Agreed that it makes sense for consistency's sake, but is it realistic? If a processor has module as the default, it might make sense to override that to install to one of the standard location. But when would you want it the other way around?

Cannot think of a case. But there is a third scenario: modules that do not have module as default, but you would still want to install new models into the module directory if possible (because you want all files to be in one place, or because there is a standalone use outside of OCR-D).

Agree, let's keep this flexible and consistent and not prevent any as of yet unanticipated use cases.
