This internal function is called by quantify_ions(). It
converts rt_limits to a data frame (since it may be a numeric vector with
two elements or a list).
replaces any infinite value with the minimum or maximum retention time.
finds the scan indices enclosed by the retention time limits.
If a retention time window does not include any scans,
scan indices are NA.

A data frame with one row per retention time window and the
calculated retention time limits and scan indices in columns rt_min,
rt_max, and scans, respectively.
