Feature Request: New style called binance-dark

Nobody has claimed this yet.

I would like to suggest the addition of a new style for the mplfinance library. The addition of this feature will improve the plot styles since there isn't a good dark style plot yet and will provide a better user experience.

I have copied the binance dark theme color scheme and code it, so I would like to propose a new style called binance_dark or somethink similar in addition to the binance style. Nevetheless, the style could be definitely be improved even more yet I would like to make the first step.

Additional context
Here is an example code snippet that demonstrates how this feature can be implemented:

```python
binance_dark = {
"base_mpl_style": "dark_background",
"marketcolors": {
"candle": {"up": "#3dc985", "down": "#ef4f60"},
"edge": {"up": "#3dc985", "down": "#ef4f60"},
"wick": {"up": "#3dc985", "down": "#ef4f60"},
"ohlc": {"up": "green", "down": "red"},
"volume": {"up": "#247252", "down": "#82333f"},
"vcedge": {"up": "green", "down": "red"},
"vcdopcod": False,
"alpha": 1,
},
"mavcolors": ("#ad7739", "#a63ab2", "#62b8ba"),
"facecolor": "#1b1f24",
"gridcolor": "#2c2e31",
"gridstyle": "--",
"y_on_right": True,
"rc": {
"axes.grid": True,
"axes.grid.axis": "y",
"axes.edgecolor": "#474d56",
"axes.titlecolor": "red",
"figure.facecolor": "#161a1e",
"figure.titlesize": "x-large",
"figure.titleweight": "semibold",
},
"base_mpf_style": "binance-dark",
}

can = pd.read_csv("data1.csv", parse_dates=True, index_col=0)
# Plot the candlestick chart
mpf.plot(
can,
type="candle",
style=binance_dark,
title="BTCUSDT",
ylabel="Price ($)",
ylabel_lower="Volume",
volume=True,
mav=(2, 4, 6),
update_width_config=dict(candle_linewidth=0.5, candle_width=0.5),
)
````

### Here is a preview of how the style of the plot looks like ##

The issue provides a proposed binance_dark style dictionary and an mpf.plot usage example, but names no source file or test. Start by locating how mplfinance defines and exposes existing styles such as binance, then compare a rendered chart with the attached preview. Done means the new style is available through the library and produces the requested dark candlestick plot.
