Version 3.5.0: Python library

• Epoch now store the time scale that they were defined in: this allows durations to be added in their respective time scales. For example, adding 36 hours to 1971-12-31 at noon when the Epoch is initialized in UTC will lead to a different epoch than adding that same duration to an epoch initialized at the same time in TAI (because the first leap second announced by IERS was on 1972-01-01), cf. the test_add_durations_over_leap_seconds test.
• RFC3339 and ISO8601 fully supported for initialization of an Epoch, including the offset, e.g. Epoch::from_str("1994-11-05T08:15:30-05:00"), cf. #73.
• Python package available on PyPI! To build the Python package, you must first install maturin and then build with the python feature flag. For example, maturin develop -F python && python will build the Python package in debug mode and start a new shell where the package can be imported.
• Fix bug when printing Duration::MIN (or any duration whose centuries are minimizing the number of centuries).
• TimeSeries can now be formatted
• Epoch can now be ceil-ed, floor-ed, and round-ed according to the time scale they were initialized in, cf. #145.
• Epoch can now be initialized from Gregorian when specifying the time system: from_gregorian, from_gregorian_hms, from_gregorian_at_noon, from_gregorian_at_midnight.
• Fix bug in Duration when performing operations on durations very close to Duration::MIN (i.e. minus thirty-two centuries).
• Duration parsing now supports multiple units in a string and does not use regular expressions. THis allows it to work with no-std.
• Epoch parsing no longer requires regex.
• Functions are not more idiomatic: all of the as_* functions become to_* and in_* also becomes to_*, cf. #155.
