* feat: bracketed paste
This introduces support for input via bracketed paste, where escape
characters in the pasted input are not interpreted.
Pasted input are marked as a special field in the KeyMsg. This is
useful because pasted input may need sanitation in individual widgets.
* fix(key): support bracketed paste with short reads
Some terminal emulators feed the bracketed paste data in multiple
chunks, which may not be aligned on a 256 byte boundary. So it's
possible for `input.Read` to return less than 256 bytes read
but while there's still more data to be read to complete a bracketed
paste input.

`WithFilter` lets you supply an event filter that will be invoked
before Bubble Tea processes a `tea.Msg`. The event filter can return
any `tea.Msg` which will then get handled by Bubble Tea instead of
the original event. If the event filter returns nil, the event
will be ignored and Bubble Tea will not process it.
As an example, this could be used to prevent a program from
shutting down if there are unsaved changes.
Based on the fantastic work by @aschey and supersedes #521.
Resolves#472.
