ColumnChunk statistics for zone mapping

[benjaminwinger]

I went a little in circles on this, trying to reduce the mess of switch cases, settling on ones using macros which I'm not overly fond of, but gets the job done at no runtime cost. I think it might be possible to create something equivalent using templates, but it's tricky.

This replaces the compression-specific data in CompressionMetadata with minimum and maximum statistics (which I considered moving out of there, but I think I prefer to keep the data separate as much as possible, since the minimum, maximum and compression type are all that's needed at the moment for the compression-related functions).

More tests are needed, including tests of tests updating and deleting nodes, and rel versions of the tests. Updates when writing don't seem to be correct as some tests are failing.
It might be useful to profile and see how much of an impact calculating the bitpacking info from the min/max has. It should be pretty fast, but also is being done for every decompressFromPage call now.

Can we add tests for MANY_TO_MANY rels?

[benjaminwinger]

I've added some very simple many to many tests (identical to the one to one). They are failing, along with a bunch of other rel tests; I don't think the statistics are working properly for those columns, which breaks how they are compressed and produces nonsense values.
