Axes take up too much memory

[James-Crean]

When loading a large file, each value an axis can be set to is loaded into react state. There are climate files with a very large number of possible values (). This causes the browser to become unresponsive for a very long time and can even cause the browser to run out of memory.

We need to drastically reduce the amount of data sent to the browser as well as make sure that the data is stored efficiently and is not duplicated.
