Hierarchy ui tree for go

Description

nvim-lspconfig displays incoming and outgoing in quickfix, which does not display hierarchical relationships and perform hierarchical expansion operations, so I wrote such a plugin.

Feature

Display the call chain of the symbol under the cursor, including incoming and outgoing <img src="https://github.com/crusj/hierarchy-tree-go.nvim/blob/main/screenshots/outgoing-1-min.png" width="850">

Expand or collapse the upper or lower call chain <img src="https://github.com/crusj/hierarchy-tree-go.nvim/blob/main/screenshots/outgoing-2-min.png" width="850">

Ability to switch window position, editor center, or bottom right corner via mapkey <img src="https://github.com/crusj/hierarchy-tree-go.nvim/blob/main/screenshots/incoming-1-min.png" width="850">

Highlight in the current module or others module

The icon of the last layer of the call chain will change to ☉
