[volume] BREAKING CHANGE - new widget instead of old ones

Having three widgets for volume led to a problem of code duplication -
same logic was duplicated three times. However when an issue was
discovered and fixed, it was fixed in only one of three widgets.
So I decided to create a volume widget from scratch, adding new
features, such as selecting input/output, better responsiveness,
easily customizable widget ui (bar, text, icon, icon and text, arc).
Should close #199, #198, #185, #182, #47, #122, #183.

-# Volumebar widget
-
-Almost the same as volume widget, but more minimalistic:
-
-![screenshot](./out.gif)
-
-Supports 
- - scroll up - increase volume, 
- - scroll down - decrease volume, 
- - left click - mute/unmute.
- 
-## Customization
- 
-It is possible to customize widget by providing a table with all or some of the following config parameters:
-
-| Name | Default | Description |
-|---|---|---|
-| `main_color` | `beautiful.fg_normal` | Color of the bar |
-| `bg_color` | `#ffffff11` | Color of the bar's background |
-| `mute_color` | `beautiful.fg_urgent` | Color of the bar when mute |
-| `width` | 50 | The bar width |
-| `shape` | `bar` | [gears.shape](https://awesomewm.org/doc/api/libraries/gears.shape.html), could be `octogon`, `hexagon`, `powerline`, etc |
-| `margins` | `10` | Top and bottom margin (if your wibar is 22 px high, bar will be 2 px (22 - 2*10)) |
-| `timeout` | 1 | How often in seconds the widget refreshes |
-| `get_volume_cmd` | `amixer -D pulse sget Master` | Get current volume level |
-| `inc_volume_cmd` | `amixer -D pulse sset Master 5%+` | Increase volume level |
-| `dec_volume_cmd` | `amixer -D pulse sset Master 5%-` | Decrease volume level |
-| `tog_volume_cmd` | `amixer -D pulse sset Master toggle` | Mute / unmute |
-
-### Example:
-
- ```lua
- volumebar_widget({
-    main_color = '#af13f7',
-    mute_color = '#ff0000',
-    width = 80,
-    shape = 'rounded_bar',
-    margins = 8
-})
- ```
-
-Above config results in following widget:

-![custom](./custom.png) 
-
-
-## Installation
- 
-1. Clone this repo under **~/.config/awesome/**
-
-    ```bash
-    git clone https://github.com/streetturtle/awesome-wm-widgets.git ~/.config/awesome/
-    ```
-
-1. Require volumebar widget at the beginning of **rc.lua**:
-
-    ```lua
-    local volumebar_widget = require("awesome-wm-widgets.volumebar-widget.volumebar")
-    ```
-
-1. Add widget to the tasklist:
-
-    ```lua
-    s.mytasklist, -- Middle widget
-        { -- Right widgets
-            layout = wibox.layout.fixed.horizontal,
-            ...
-            --[[default]]
-            volumebar_widget(),
-            --[[or customized]]
-            volumebar_widget({
-                main_color = '#af13f7',
-                mute_color = '#ff0000',
-                width = 80,
-                shape = 'rounded_bar', -- octogon, hexagon, powerline, etc
-                -- bar's height = wibar's height minus 2x margins
-                margins = 8
-            }),
-
-            ...
-    ```
-
-## Troubleshooting
-
-If the bar is not showing up, try to decrease top or bottom margin - widget uses hardcoded margins for vertical alignment, so if your wibox is too small then bar is simply hidden by the margins.
