Runs out of /tmp space. Needs option to specify temp dir

[GabeAl]

On modern systems, /tmp redirects to RAM.
On a 1tb RAM node, the 500gb of RAM in /tmp is easily exhausted during the diamond run if multiple instances are running with hundreds/thousands of MAGs each.

The solution is to allow the user to specify temporary directory. If this is already possible, I don't see a flag for it.

Results are sometimes silently corrupt if the diamond blast file is truncated once /tmp is exhausted.

Thanks for raising this. Implemented in release 1.0.1
