Evgenii Stratonikov 5073a37930 [#1433] metabase: Optimize Select 
For some filters we can scan only a subset of keys instead of checking
each key.

```
name                       old time/op  new time/op  delta
Select/string_equal-8      49.3µs ± 4%  11.0µs ± 4%  -77.68%  (p=0.000 n=10+10)
Select/string_not_equal-8  7.01ms ± 5%  7.06ms ±10%     ~     (p=0.971 n=10+10)
Select/common_prefix-8      118µs ± 6%    79µs ± 5%  -33.04%  (p=0.000 n=10+9)
