<description>
Splits a string using a [code]delimiter[/code] and returns a substring at index [code]slice[/code]. Returns an empty string if the index doesn't exist.
This is a more performant alternative to [method split] for cases when you need only one element from the array at a fixed index.
Example:
[codeblock]
print("i/am/example/string".get_slice("/", 2)) # Prints 'example'.
[/codeblock]

<description>
Splits the string by a [code]delimiter[/code] string and returns an array of the substrings. The [code]delimiter[/code] can be of any length.
If [code]maxsplit[/code] is specified, it defines the number of splits to do from the left up to [code]maxsplit[/code]. The default value of [code]0[/code] means that all items are split.
If you need only one element from the array at a specific index, [method get_slice] is a more performant option.
Example:
[codeblocks]
