clang: format file

just found out that clangd-lsp supports reading the .clang-format file, and apply the formatting options to a current project in nvim.

to make it work just create .clang-format file in the project root:

BasedOnStyle: Chromium
TabWidth: 4
IndentWidth: 4
UseTab: Always
ColumnLimit: 120

then ask LSP to reformat your code with :lua vim.lsp.buf.format().
