File add emits as many change events as chunks written

[francescochiapello]

On linux environment - Docker container with Ubuntu 18.04 - when a file is large (> ~ 1Mb) and is written in the watched folder, nsfw emits lots of change events that are supposed to be the chunks written on the file system.

It would be useful to optimize nsfw preventing chunks change events for examle adding an option to be passed to the watch instance.

How can you distinguish between a chunk or an actual change to the file?
