Khoward height max vertical velocity

[Katie-Howard]

Addresses #GitHubissuenum

This is a plugin to find the height at which a maximum occurs. This is for the Maximum vertical velocity workflow. We need to know the height at which the maximum occurs for our meteorologists to help them identify lee waves.

Testing:

• [x] Ran tests and they passed OK
• [x] Added new tests for the new feature(s)

Acceptance test data is here: https://github.com/metoppv/improver_test_data/pull/51

[Katie-Howard]

I have a notebook within information on the acceptance test data that can be accessed through /data/users/khoward/EPP_data/max_vertical_velocity/vertical_velocity.ipynb

[Katie-Howard]

I have changed the acceptance tests data to reduce the size of it - but wasn't able to recreate the kgo @mspelman07 can you do this? It was doing weird errors when I tried. I've put pushed up a latest version of the data without the kgo, but if you need the old data it can be found here: /data/users/khoward/EPP_data/max_vertical_velocity/old_data

[mspelman07]

I have update the acceptance test data including regenerating the kgo. I found the errors were being caused by a mislabelled file in the acceptance test data. I've updated this but as I can't push to this PR I have created a new PR: https://github.com/metoppv/improver/pull/2020 to replace this one.

As such I'm closing this PR as it has been superseeded.
