Funny parsing results

[xeruf]

Wrote a small helper to compare to chrono-english.
Apart from #23 and #83, I found some other small issues:

• year ago produces a one-day offset, presumably because of leap years not being accounted for
• today, while being consistent in both tools, I would expect to refer to the day start rather than the current time
• -1h1m should be 61 minutes ago, the preceding minus shall negate the whole expression. It should understand -1h +1m for 59 minutes ago.

@conradludgate might also be interesting for your fork https://github.com/conradludgate/interim, which will be my preferred parser with fallback to this one, because each handles some relative times better:

• unlike the others, parse_datetime can handle plain expressions like week, fortnight, day and stacked relative times such as -1h1m, and handle a + prefix as well as last and next
• I see no relevant differences in what interim and chrono-english understand - they understand shorthands for day(d) and year(y) unlike parse_datetime, as well as calculating month and year offsets more accurately
• none of these libraries can handle in X expressions (in 1 hour should be equivalent to +1h) as well as DATE at TIME
• all libraries handle -X and X ago for day, hour, minute, second

Irrelevant sidenote: Only chrono-english understands 1se and 1M.

with years business gets funny:

For interim, I intended to keep all the quirks of chrono-english for compatibility, but with less panics. I'll admit I haven't given too much thought to the actual cases. I'm open to adding new features if desired

@conradludgate that would be great, if you could add these I could fully rely on interim: conradludgate/interim#7

@xeruf you could please replace your screenshots by text?
They are terrible for search, reproducibility and accessibility
