LimitFilter

[wojteninho]

Say we want to filter first 100 files from a particular directory. I would love to do it as easy as:

s := NewBuilder().
     Files().
     In("/my/photos").
     Limit(100)    
     MustBuild()

for item := range MustScan(s.Scan(context.TODO())) {
    ...
}

Behind the scenes, it should be the new Scanner implementation called LimitScanner which is not a self-sufficient scanner, but act as a wrapper above the concrete scanner.

basicScanner := NewBasicScanner(WithDir("/my/photos"))
limitScanner := NewLimitScanner(basicScanner, 100)

To get familiar with the idea of wrappers check out available wrappers implementations.

Happy to see PR with this feature :-)
