v0.3.3

Added

• Module pathway.dt to construct and manipulate DTypes.
• New argument keep_queries in pw.io.http.rest_connector.

Changed

• Internal representation of DTypes. Inputting types is compatible backwards.
• Temporal functions now accept arguments of mixed types (ints and floats). For example, pw.temporal.interval can use ints while columns it interacts with are floats.
• Single-element arrays are now treated as arrays, not as scalars.

Fixed

• to_string() method on datetimes always prints 9 fractional digits.
• %f format code in strptime() parses fractional part of a second correctly regardless of the number of digits.
