fix: virtual cursor hl overwhelme by search hl

[henry-hsieh]

Currently, hop uses combine hl mode on virtual text. If the search highlight is bright color, the virtual text became hard to recognize. The fix change the hl mode to replace.

Another option is to dim the search highlight together with original text.

I like the current behavior better, however let's keep this open for other users to weigh in on the decision.

[henry-hsieh]

Highlights are subjective. I can make it becomes a hop option. Users can configure it based on their needs.

Have you tried changing extmark priority? I don't have access to nvim for checking it right now.

[henry-hsieh]

I think it has nothing to do with priority. Because hop doesn't specify the background colors on highlights for extmarks. By using combine method, it will preserve any background colors of users' colorscheme based on highlights of texts.

I'm okay with search highlight being dimmed by hop. That would be the most optimal looking by users. For example, apply a light gray color to search highlight in hint state, and recover after leaving hint state.

In that case let's make ‘hl_mode‘ configurable.

OK! I have updated the new commit with hl_mode option.
