Operation request: Respace / Chunks

## Summary
Add given whitespace (or any custom delimiter; I can imagine space and newline being the most useful) at regular intervals to a string. The use case is to separate a large block of text data into chunks.
### Example Input
010010000110010101101100011011000110111100100000010101110110111101110010011011000110010000100001 with interval 8 and delimiter space
### Example Output
01001000 01100101 01101100 01101100 01101111 00100000 01010111 01101111 01110010 01101100 01100100 00100001
