add support for "maxRelativeTimeUnit" for .fromNow() and .from()

[kimmanwky]

What does this PR do?

Add new optional parameters ("maxRelativeTimeUnit") for methods - Jiffy().fromNow() and Jiffy().from().

This parameters allow the relative time to be shown at defined maxRelativeTimeUnit (minute, hour, day, month).

For example,

"[in] 365 days [ago]", instead of "[in] 1 year [ago]"
"[in] 60 days [ago]", instead of "[in] 2 months [ago]"
"[in] 48 hours [ago]", instead of "[in] 2 days [ago]"
