Add support for 'd', 'mm', 'y'

[Miserlou]

Go doesn't allow these values, but we're not bound by their restrictions.

Even if they're not available by default, it'd be useful to allow these values for our purposes.

[Miserlou]

1 day = 24h, 1mm = 30d, 1y = 365

No need for any further precision than that, IMO.

I have code that depends on it being compatible with Go's format. I'd be open to adding some additional methods with this behaviour. Do you have a preference on the naming?

[Miserlou]

Just what I stated on the naming.

I think Go-compatibility is probably the most useful by default, but perhaps these be enabled by setting extended=True to the API.

Alternate ideas could be go_compatible=False, or a dict of allowed values and what they map to, so I could extra_tokens={'mm': 31}.

I just pushed some code to master. Thoughts?

durationpy.to_str(ts, extended=True)

[Miserlou]

I like it!

tagged and published.

Sweet!

[Miserlou]

Any chance we can get this added to from_str as well? :)

[icholy]

@Miserlou should already work. No need for the flag because it's backward compatible.

[Miserlou]

Oooh, ok.
