* Remove calls to nvim_err_writeln

Instead use `vim.deprecate` and `error`

* Fix bug of repl not being properly cleaned

* Add indirection to opening new float windows

This allows for functions to be reused to move/reshape float windows

* Add functions for managing the window

This ensures we can move the window around

* Rework view

The intent of this commit is to:
  - Allow for a more fluid split definition
  - Allow for custom sizing (percent and function based)
  - Remove the noise in opening floats
  - Allow for reconfiguring floats

* Sketch implementation of multiple views

* Fix deprecation message

* Add a bit more description to README

* Add documentation to view.lua

* Make helper functions take orientation

So then they're simplified

* Document new view API

* Change default to splits

Ref Vigemus#248

* Allow view API to take options

* Add example for configuring options in windows

* Fix broken fallback to command string

* Fix setting buffer

* Add more examples to readme

Fix nil table for options

* Allow fractions in views

* Add even more docs

* feat: allow to build the repl command using a lua function

This is useful e.g. if the command has to take a path or directory
as an argument.

* feat: pass current buffer to repl command
