This PR adds the custom solution for streaming CloudFormation events into a structured table with a column of fixed width, to prevent "jumping"

Before:

After:

The new approach uses Reflection and pretty complex but seems to work well.

// Format reads the struct tag `width:"<width>,<space>"`
// further marshaling into structured field
func (s *stackEvent) format(fil filters) []byte {
tp := reflect.TypeOf(s).Elem()

Do you think it would be possible to add table unit tests for that method which seems central? It would help the understanding, document a bit the look of the output, put non regression in place and allow future safe refactoring.

I do not have the answer, I am just wondering.

Tailers are experimental and are not advertised on the sub commands listing, so we have more leeway in their implementation. So we shall review that and it could make it into the 0.1.10 that is due in the next 2 days.

Otherwise thanks for the work @trane9991 !
