Updated to latest, string unix timestamp is not understood by 'get'

[sebtrack]

Issue Description

import arrow

arrow.get('1657831049')

results in

arrow.parser.ParserError: Could not match input '1657831049' to any of the following formats: YYYY-MM-DD, YYYY-M-DD, YYYY-M-D, YYYY/MM/DD, YYYY/M/DD, YYYY/M/D, YYYY.MM.DD, YYYY.M.DD, YYYY.M.D, YYYYMMDD, YYYY-DDDD, YYYYDDDD, YYYY-MM, YYYY/MM, YYYY.MM, YYYY, W.

worked beforehand but with the latest version it does not.

We would like to accept a lot of time formats and some of them are strings some of them are unix timestamps, so forcing a int/float conversion is unacceptable. It would be nice to use string unix timestamps.

@krisfremen @systemcatch @jadchaar any insight on this?

From reading the release history, this behavior was intentionally changed in version 0.15.0 "to support the ISO 8601 basic format and to address bugs such as #447". Is this really something that people would want to revert?

@krisfremen @jadchaar @systemcatch could you elaborate more for @13MK3
