Proposal to update description of ctags in README.md

[hirooih]

Many of the same questions and requests related to ctags have been registered in issues, #66, #84, #130, #142, and #151.

Proposal 1

Add the following your comment in ctags-integration section of README.md.

Currently the extension supports only tags for one file (the currently open file) and not the entire work space.

Proposal 2

Introduce extensions for ctags to support tags for any files.

For example ctags companion extension works great with this extension as I commented in Dec, 2020

Just add the following settings on .vscode/settings.json in your workspace.

{
    "ctags-companion.command": "ctags -R --fields=+nKz -f .vscode/.tags --langmap=SystemVerilog:+.v -R rtl /opt/uvm-1.2/src",
    "ctags-companion.readtagsEnabled": true,
}

It supports files not only in the workspace, but also outside the workspace. (ex. /opt/uvm-1.2/src in the example above)

It also recently added support for the readtags command in the Univsersal Ctags distribution, which allows for faster searches even on large projects.
