Increase default TPC-H benchmark iterations (#2840) Seems like TPC-H is quite noisy, even on disk. Doubling the iterations will hopefully help a bit with the noise while not making a huge difference in overall benchmark runtime (When running on disk - it might even still be slower than building the binary). Also changed a bunch of string-based `default_value` to `default_value_t` which takes on the post-parsing value.

Invert compression ratio in `BtrBlocksCompressedWriter` (#2839) compression ratio is often [defined](https://en.wikipedia.org/wiki/Data_compression_ratio#Definition) as `before / after` ("higher is better"), that's also what we do in the BtrBlocks compressor, so it seems like making it consistent across the codebase makes sense. ~I thought there's another place we use the term, but I couldn't find it.~ I think it was when we store the previous chunk's compression ratio, got it before merging.

Btrblock compress string to constant (#2830) While the compress does return small dicts with 0-width bitpacked codes, I think we should instead return a constant array here
