feat: bulk image upload

[mfw78]

Problem

When uploading the metadata, the URI, and therefore CID for any photos / images also needs to be set.

Solution

When uploading a facility level metadata, allow multiple --image command line options in lpms-cli, then have all these images upload to IPFS, get the cid, then insert this in-line in the facility level metadata before it's pushed to lpms-server and onto IPFS.

The same workflow above can be done when pushing space level metadata.

Moving this issue to lpms-cli repo.
