Full Diff: 1.2.0...1.2.1

• [NEW] Added Albanian, Tamil and Zulu locales.
• [NEW] Added support for Decimal as input to arrow.get().
• [FIX] The Estonian, Finnish, Nepali and Zulu locales now support dehumanize.
• [FIX] Improved validation checks when using parser tokens A and hh.
• [FIX] Minor bug fixes to Catalan, Cantonese, Greek and Nepali locales.

• [NEW] Added Odia, Maltese, Serbian, Sami, and Luxembourgish locales.
• [FIXED] All calls to arrow.get() should now properly pass the tzinfo argument to the Arrow constructor. See PR #968 for more info.

• [CHANGED] Renamed requirements.txt to requirements-dev.txt to prevent confusion with the dependencies in setup.py.
• [CHANGED] Updated Turkish locale and added tests.

• [NEW] Implemented the dehumanize method for Arrow objects. This takes human readable input and uses it to perform relative time shifts, for example:

    >>> arw
    <Arrow [2021-04-26T21:06:14.256803+00:00]>
    >>> arw.dehumanize("8 hours ago")
    <Arrow [2021-04-26T13:06:14.256803+00:00]>
    >>> arw.dehumanize("in 4 days")
    <Arrow [2021-04-30T21:06:14.256803+00:00]>
    >>> arw.dehumanize("in an hour 34 minutes 10 seconds")
    <Arrow [2021-04-26T22:40:24.256803+00:00]>
    >>> arw.dehumanize("hace 2 años", locale="es")
    <Arrow [2019-04-26T21:06:14.256803+00:00]>

• [NEW] Made the start of the week adjustable when using span("week"), for example:

    >>> arw
    <Arrow [2021-04-26T21:06:14.256803+00:00]>
    >>> arw.isoweekday()
    1 # Monday
    >>> arw.span("week")
    (<Arrow [2021-04-26T00:00:00+00:00]>, <Arrow [2021-05-02T23:59:59.999999+00:00]>)
    >>> arw.span("week", week_start=4)
    (<Arrow [2021-04-22T00:00:00+00:00]>, <Arrow [2021-04-28T23:59:59.999999+00:00]>)

• [NEW] Added Croatian, Latin, Latvian, Lithuanian and Malay locales.
• [FIX] Internally standardize locales and improve locale validation. Locales should now use the ISO notation of a dash ("en-gb") rather than an underscore ("en_gb") however this change is backward compatible.
• [FIX] Correct type checking for internal locale mapping by using _init_subclass. This now allows subclassing of locales, for example:

    >>> from arrow.locales import EnglishLocale
    >>> class Klingon(EnglishLocale):
    ...     names = ["tlh"]
    ...
    >>> from arrow import locales
    >>> locales.get_locale("tlh")
    <__main__.Klingon object at 0x7f7cd1effd30>

• [FIX] Correct type checking for arrow.get(2021, 3, 9) construction.
• [FIX] Audited all docstrings for style, typos and outdated info.

• [FIX] Updated internals to avoid issues when running mypy --strict.
• [FIX] Corrections to Swedish locale.
• [INTERNAL] Lowered required coverage limit until humanize month tests are fixed.

• [FIXED] Fixed an OverflowError that could occur when running Arrow on a 32-bit OS.
