feat(#48): `accept_line` keymap option

[AlejandroSuero]

With this PR accept_line keymap is introduced with <C-l> as default because l -> line.

Accepts the next suggested line by looking for end of line.

• [x] Updated README.md with the keymap changes.

Closes #48.

Awesome! there's only one thing, when the suggestion is indented and you accept_line it will only accept the indetation space but not the whole line.

Look at this video when the indentation is deep, you have to press accept_line multiple times to actually accept the line.

Every time I press accept_line it accepts one indentation level.

@pedro757 I made the changes so it gets the following line as a whole:

[!NOTE] If you insert a new line by yourself and needs indentation, it will have the same effect as in your video, for that line.

I am trying find a way that doesn't accept the whole suggestion as sometimes it gets the full suggestion in this case. It the same behaviour with accept_word and accept_suggestion. So this is following the current behaviour for the other keymaps.

LGTM, it feels much better now, thank you!
