Create a function that takes a string of 1's and 0's (binary) as an argument and return the equivalent decoded ASCII text. Characters can be in the range of "00000000" to "11111111", which means every eight digits of binary input represents a single character.
If you were to combine these characters into the string "abc", the corresponding binary would be 011000010110001001100011.
binary_conversion("011001010110010001100001011000100110100101110100") ➞ "innokodakademija"
binary_conversion("001100010011001000110011") ➞ "123"
binary_conversion("010010000110010101101100011011000110111100111111") ➞ "Hello?"
If you are given an empty string as input, you must also return an empty string. Otherwise, the input will always be a valid binary string.
