lualine defines two kinds of separators:
- `section_separators` - separators between sections
- `components_separators` - separators between components in sections
- `section_separators` - separators between sections
- `components_separators` - separators between the different components in sections
```lua
options = {
section_separators = { left = '', right = ''},

section_separators = { left = '', right = '' },
component_separators = { left = '', right = '' }

Here left means it'll be used for left sections (a, b, c) and right means
it'll be used for right sections (x, y, z).
Here, left refers to the left-most sections (a, b, c), and right refers
to the right-most sections (x, y, z).
