Substring(s) of an ANSI colored string

This is the color-aware counterpart of base::substring. It works exactly like the original, but keeps the colors in the substrings. The ANSI escape sequences are ignored when calculating the positions within the string.

Usage
col_substring(text, first, last = 1000000L)
Arguments
text
Character vector, potentially ANSI styled, or a vector to coarced to character. It is recycled to the longest of first and last.
first
Starting index or indices, recycled to match the length of x.
last
Ending index or indices, recycled to match the length of x.
Value

Character vector of the same length as x, containing the requested substrings. ANSI styles are retained.
