Floats in humanize output for languages overriding _format_timeframe

[krisfremen]

Issue Description

Doing humanize on languages that override _format_timeframe is spitting out floats instead of integers which is not nice on the eye.

arrow.utcnow().shift(weeks=5).humanize(locale="en", granularity="day")
'in 35 days'
arrow.utcnow().shift(weeks=5).humanize(locale="bg", granularity="day")
'напред 35.0 дни'
arrow.utcnow().shift(seconds=55000).humanize(locale="bg", granularity="minute")
'напред 916.6666666666666 минути'

I would be interested in fixing this issue. Is this still open or has someone else decided to fix it?

[krisfremen]

Hmm, I must've not pushed my fixes. I have two fixes, one of which breaks some tests due to ints vs floats.

Will push soon.

I can give this a try as well!
