[Feature Request]: Ability to keep pick closer open after closing a tab

### What?

The ability to close multiple tabs with the pick closer, just as you would with closing one but without the mode exiting after the first. For instance:
:BufferLinePickClose
e t q // close tabs denoted by e, t, q.
// Press escape to exit pick closer mode

### Why?

Removes the need to run BufferLinePickClose after you close each tab, speeds things up if you have more than one tab you want to close. If you feel like you don't want to implement this, I'll try myself, just need to see the relevant lines of code or any recommendations.
