There is two issues.

1. For example, I want treat with "-t" option two files in the same directory:

IMG_20210101_123456001.jpg
IMG_20210101_123456002.jpg

The second run will fail, because these files should have the same name. Is it possible to add optional additional numeric extension like Android camera does? Like this:

20210101_123456.jpg
20210101_123456_1.jpg

2. Google Camer

We used to have this (tracked in felixc/rexiv2#18, set up in felixc/rexiv2@90ae678), but it had to be removed in felixc/rexiv2@1aff63e because the travis-cargo project we'd been using had broken ages ago was no longer actually uploading coverage info.
