Optimize format performance
...
As seen in the https://rust.godbolt.org/z/Y8djWsq1P - write! macro produces significantly more code than a write_str call, so this change should have somewhat better performance. To my knowledge, a lot of ppl tried to solve this optimization in the compiler, but no luck yet, so may help compiler ourselves for now.

Implements SEP-0002 ADJUST function
...
ADJUST is now only implemented when a new timezone is given. I am not sure "" for no timezone is the best way to go.
It is behind a sep-0002 feature in spargebra and sparql-smith and enabled by default in oxigraph.
