TimeframeToMinutes

The timeframeToMinutes() function returns the number of minutes in an arbitrary timeframe string.
timeframeToMinutes()
Returns the number of minutes in the supplied timeframe string, which is arbitrary, i.e. it doesn't have to be the timeframe of the current chart but can be taken from an input.
The sole advantage over the short and neat Pinecoders f_resInMinutes function from their excellent MTF Selection Framework (at tradingview.com/script/90mqACUV-MTF-Selection-Framework-PineCoders-FAQ/) is that this one doesn't use up a security() call.
To convert the other way, from minutes to timeframe.period format, I would use the f_resFromMinutes function from the Pinecoders' MTF Selection Framework, which does not use security().
ERROR-CHECKING: It has light error-checking to try to make sure the string is in the format timeframe.period, e.g. 15S, 1 (minute), 60 (1H), 1D, 1W, 1M.
It will throw an error for some non-standard timeframes such as 30 hours (1800 minutes). Above 1440 minutes, only whole numbers of days are allowed. This is to be consistent with the security() function.
But it will allow some non-standard timeframes such as 7 hours (420 minutes). Such timeframes must still be supplied in the standard timeframe.period format.
param _tf
The timeframe to convert to minutes. Must be in timeframe.period format.
returns
An integer representing the number of minutes that the timeframe period is equivalent to.
Updates:
Added a specific error condition if the input timeframe is empty, not just "Badly formed".
Added a commented-out example of how to prevent this error when calling the function.
