 -- [ strsplit ]
--- Splits a string using a delimiter. Self-contained on purpose: it does NOT
--- delegate to the global strsplit / string.split, because third-party addons
--- clobber those (e.g. BigWigs' SpellRequests redefines string:split to return
--- a table, which would make this return a single table instead of r,g,b,a and
--- break color/version parsing depending on load order). Delimiter chars are
--- treated as a set (any one char splits), and empty fields are preserved
--- ("a,,b" -> "a", "", "b"), matching real strsplit semantics.
--- 'delimiter'  [string]        characters that will be interpreted as delimiter
---                              characters (bytes) in the string.
--- 'subject'    [string]        String to split.
--- return:      [list]          a list of strings.
