Optimise memory on exports

Issue #116 new
Ed McDonagh created an issue

A 6500 study CT xlsx export was killed because the computer it was running on ran out of memory.

xlsxwriter has a memory optimisation mode that might solve this - there are restrictions though on how data is written, as each row is flushed to disk in turn, meaning you can't go back.

Need to establish whether this has any consequences.

    Optimisation still needs to be done, and the memory optimisation mode might be part of this. But I haven't seen this issue since, and I haven't changed how much memory is available, so I will take it out of the docs.
