Describe the bug

I see the below error when I attempt to run :DataViewer for the 2nd time on a .csv buffer. This comes about if I've opened a CSV file and used DataViewer floating window to look at it for a bit, then close DataViewer, but then want to use it again.

Error executing Lua callback: ...k/paqs/start/data-viewer.nvim/lua/data-viewer/module.lua:109: Vim:E95: Buffer with this name already exists
stack traceback:
        [C]: in function 'nvim_buf_set_name'
        ...k/paqs/start/data-viewer.nvim/lua/data-viewer/module.lua:109: in function 'create_bufs'
        ...ite/pack/paqs/start/data-viewer.nvim/lua/data-viewer.lua:64: in function <...ite/pack/paqs/start/data-viewer.nvim/lua/data-viewer.lua:28>

It does not appear to happen with view = { float = false }

Steps To Reproduce

1. open a .csv file
2. run :DataViewer
3. close the DataViewer floating window with :q
4. run :DataViewer again

Expected Behavior

the DataViewer window should open again
