Write a function, decompress_braces, that takes in a compressed string as an argument. The function should return the string
decompressed.
The compression format of the input string is 'n{sub_string}', where the sub_string within braces should be repeated n times.
You may assume that every number n is guaranteed to be an integer between 1 through 9.
You may assume that the input is valid and the decompressed string will only contain alphabetic characters.
