Thanks to @olivierlesnicki.
Pumped version and also prefixed the id of the generated canvas element with 'filtrr2-' so that we don't end up with two ids that are the same.
The only available option now is 'store'. By setting it to false, one can force the constructor not to cache itself. This gives the benefit to re-create Filtrr2 instances on the same elements.
