Write a program by Python to run a Run Length Encoding that includes three functions:

1, RLE_encode() -> to encode the string

2, RLE_decode() -> to decode the string

3, RLE_compression_ratio() -> to compute the compression ratio

Please run the function with the below example: Gooooooooooooo!

- With RLE, we can represent them with 1G1301 !, which contains only 7 characters, so only 7 bytes are needed for encoded text - With respect to the original message size (15 bytes), the compression ratio is 15:72.14:1 - RLE is a lossless compression method
