[Bug]: E5108 invalid key

[Iron-E]

Hello,

I was testing out this plugin after getting an issue on one of my plugins (Iron-E/nvim-libmodal#18), and wanted to post some new examples for integration with statuslines. However, I've been having trouble— I get E5108 when calling setup. I've produced a minimal example:

vim.api.nvim_set_hl(0, 'Foo', {})
require('heirline').setup {statusline = {{hl = 'Foo', provider = 'Test'}}}

The error is this:

E5108: Error executing lua ...hare/nvim/lazy/heirline.nvim/lua/heirline/highlights.lua:33: invalid key:                                                
stack traceback:

        ...hare/nvim/lazy/heirline.nvim/lua/heirline/highlights.lua:33: in function 'make_hl'

I'm using Neovim 0.8.3, and commit 81ceb3025e6c7030c42accc3951dad94f31ff0c8 of this plugin. Let me know if I'm just missing something.

Thanks for the quick help. I was able to fully port my statusline over in no time.
