doc: "Takes a string and a seperator, searches the string for all instances of the seperator, and returns a temp array filled with the pieces of the string split at each instance. If you give an empty string as the seperator, the string is split into individual characters. You can use this to search for a substring in a string like this: `strlen(get_array(string_split(haystack, needle), 0))`"

Cuts a substring from a string starting at "start" up to "length" characters. The first character position is 0 (zero).
- If start is negative - it indicates starting position from the end of the string (for example `substr("test", -2, 2)` will return last 2 charactes: "st").
- If length is negative - it means so many characters will be omitted from the end of string (example: `substr("test", 0, -2)` will return string without last 2 characters: "te").
- If length is zero - it will return a string from the starting position to the end of the string **New behavior** for sfall 4.2.2/3.8.22

Returns position of a first occurance of a needle string in a haystack string (starting from a given 0-based position), or -1 if not found.
- If pos is negative - it indicates starting position from the end of the string, similar to substr().
