706 writing large volume of data

[mauzey1]

Resolves #706

This PR will replace the use of int with size_t in the function cmor_write_var_to_file when calculating the number of elements in an array. This will allow cmor_write to write data arrays with more than 2^31-1 elements.

@mauzey1 this is great, thanks!

There maybe some very subtle changes required to deal with the new MIP-cmor-tables, a string -> list type change for coord descriptions, so then we can wrap that up as 3.7.3 or 3.8 if the osx-arm64 change happens in the same release

We'll need to check on those Linux build failures too

Could you elaborate on this feature? Please post an issue detailing it.

The conda rerender step is taking too long when installing packages for some reason. I encountered that issue when working on another branch but I was able to resolve it by just rerunning the failed workflows. I will try rerunning them after the OSX builds are done.

@mauzey1 will do (post a new issue). I am travelling next week and will meet with Matt in person, so we can figure out what is required and document that in an issue.

And yep, you're right, second pass on circleci passes fine
