extractAllGroups(haystack, re_needle) function
Function that extracts from haystack all matching non-overlapping groups with regular expressions,
and put those into Array(Array(String)) column.
Example:
:) SELECT extractAllGroups('abc=111, def=222, "jkl mno"="444 foo bar"', '("[^"]+"|\\w+)=("[^"]+"|\\w+)');
┌─extractAllGroups('abc=111, def=222, "jkl mno"="444 foo bar"', '("[^"]+"|\\w+)=("[^"]+"|\\w+)')─┐
│ [['abc','def','"jkl mno"'],['111','222','"444 foo bar"']] │
