mb_str_split signature missing

[bitwise-operators]

PHP 7.4 added the mb_str_split function to the multibyte string library.

However, it appears to be missing form the CallMap_74_delta.php dictionary, as well as from the main CallMap.php

I believe the signature should be:

'mb_str_split' => ['list<string>', 'string'=>'string', 'limit='=>'int', 'encoding='=>'string|null'],

Hey @bitwise-operators, can you reproduce the issue on https://psalm.dev ?

I found these snippets:

https://psalm.dev/r/3d06280737

<?php
//	This works
function getFirstChar(string $input):string {
	$chars = str_split($input);
    return $chars[0] ?? '';
}

//	Should be the same
function getFirstCharMultibyte(string $input):string {
	$chars = mb_str_split($input);
    return $chars[0] ?? '';
}

Psalm output (using commit 00c0622):

INFO: MixedAssignment - 10:2 - Unable to determine the type that $chars is being assigned to

INFO: MixedArrayAccess - 11:12 - Cannot access array value on mixed variable $chars

INFO: MixedReturnStatement - 11:12 - Possibly-mixed return value

INFO: MixedInferredReturnType - 9:47 - Could not verify return type 'string' for getFirstCharMultibyte

Thanks!

Do you mind adding that to the callmap yourself?

Sure, I'll have a look
