Due to the significant discrepancy between Kitty's actual behavior and what is described at https://rockorager.dev/misc/bracketed-paste-mime/ I wrote up a Gist describing how the spec is actually implemented in Kitty. |

Rationale of this PR
Adds support for using OSC 5522 (Kitty Clipboard Extension) to read and write all mime types from the system clipboard.
The main protocol can be found here: https://sw.kovidgoyal.net/kitty/clipboard/#copying-all-data-types-to-the-clipboard
The specification for paste events can be found here: https://rockorager.dev/misc/bracketed-paste-mime/
In cases where Kitty's implementation differs from the above specifications I have followed Kitty's implementation.
This pr implements support for copying and pasting
text/uri-listas well astext/plain. The paste events have been exposed to lua similarly to drag and drop allowing supporting more formats easily. I have left the existing clipboard functions as is soya.clipboard()and similar continue to use external clipboard tools. In the case of the copy keybindings support for OSC 5522 is detected and OSC 5522 is used if available, otherwise the original clipboard commands are used.For now I have left the same 1MB size limit as the drag and drop however this will need to be revisited to support directly pasting files such as images from the clipboard.
I have tested this with Kitty 0.47.1
