* Added `\lpy` mode to run python commands and interact with DataFrames on Python way.
* Added `/t ` query output modifier to show rows as transposed table. Add it to the end of query.
* Added table info when the query contains only table name.
* Changed behaviour to read json per line files. Now every json line will be normalized and for json `{"a":{"b":1}}` will be created one column `a.b` with `1` value. Arrays `[1,2,3]` become strings. This allows to operate with nesting json as columns.
* Fixed autocomplete for column names with special characters.
