My PR #972 always keeps breaking when there are changes in how Btree

e67f56bb3d Merge 'Setup tracing to allow output during test runs' from Preston Thorpe
## The problem:
Sometimes you want to run the tests _and_ look at logs, and previously
that wasn't possible because all the tests relied on stdout/stderr.
## The solution:
Setup `tracing-appender` to automatically log to a designated
`testing/test.log` when `RUST_LOG` is set.
This PR also starts a `testing.md` file describing testing in limbo. My
hope is that people who know stuff about DST and the fuzzing setup will
fill in the TODOs :)

aa6e2d853a Merge 'Support backwards index scan and seeks + utilize indexes in removing ORDER BY' from Jussi Saurio
## Main stuff
- Support iterating an index backwards
- Support scanning an index (instead of seeking with a condition)
- Support backwards index seeks
- Support backwards rowid seeks
- Fix existing backwards iteration logic for table btrees
- Remove ORDER BY entirely if any index satisfies the ordering
- Add fuzz tests for rowid seeks, 1 and 2 column index seeks
## Bytecode examples (note the lack of order by sorting):
one column index order by, forwards:

7435d005db Merge ' allow insertion of multiple overflow cells ' from Pere Diaz Bou
With big cells it is easy to see multiple overflow cells happen while
balancing. Previously we disallowed insertion with > 1 overflow cells,
let's fix this by allowing it as we should be safe now.
This pr also adds some more comments to the balancing algorithm.
