Add data-lazy-offset attribute option

This commit adds a new data-lazy-offset attribute which can be used to
optionally specify the waypoints offset for lazy loading.

This uses the same values as the waypoints plugin offset option.

This is used when you want to specify a different offset value than the
default 120%.
