rapt offline mode

[OH-AU]

In ticket #10 there is a reference to running rapt in offline mode. We also have a need to do this. I've managed to modify the python script so it uses a local rapt.sif image via singularity. lsof confirms it's using the local image, but the last statement when running the --test says: [2023-04-21 16:44:04] Running functional tests... With no further activity as it can't access the internet. Using an actual fastq file for input, the program appears to run as expected, but after completing with DONE, it seems to hang at "Error sending metrics to NCBI ..." without ever returning a prompt. When using a real it tries to download more data from amazon.

Summary: Could the instructions on running locally be made publicly available. The compute nodes on the cluster have no/limited internet access (same as I suspect the user in #10) so an offline option is the only way we can get usage of the tool. Thanks.
