Returns the reduction ratio associated with a blocking method

1 | ```
reduction.ratio(block.labels)
``` |

`block.labels` |
A list of the blocks labels. |

The reduction ratio

1 2 3 | ```
tlsh.blocks <- block_setup_v2(r.set = RLdata500[1:50,c(-2)], b=22, save_signature=FALSE, k=2)
block.ids <- block.ids.from.blocking(tlsh.blocks)
reduction.ratio(block.ids)
``` |
