Release version 0.10

[moloney]

We are long overdue for a release, especially with the recent merge of multi-frame support. However there are also a number of changes to the meta data structure happening that I would like to mostly stabilize before making a release, in particular deciding if PR #96 should be merged. There is also just a lot of cruft that I would like to see taken care of.

So roughly the task list is:

• Test PR RF: Use csa_header package to parse Siemens CSA headers #96 on more real world data
• Get CI updated and functional again
• Switch from setup.py to pyproject.toml
• Look into tools to assist with cutting releases
• Update documentation to reflect recent changes, get RTD working again or switch to gh-pages
