Selectable text in mvLogger

[JERisBRISK]

Is your feature request related to a problem? Please describe.
I use mvLogger a lot to print out interesting things about my application as I'm designing, debugging, etc. However, the text is not selectable nor copyable. It would be much more beneficial if it was.

Describe the solution you'd like
Make the text in the mvLogger not just a rasterized font display, but an actual text control that supports range selections, select all, copy, etc., via standard keyboard shortcuts and a context menu.

Describe alternatives you've considered
If I need the text output currently, I dump the text I want to a log file and then keep a text editor open to that secondary log stream. Not quite as convenient, but it works.

Additional context
n/a

My hack is to replace the text widget with an input_text in the log() method:

# Allows selecting and copying the text line by line
new_log = dpg.add_input_text(
    width=-1,  # Full
    parent=self.filter_id, filter_key=message,
    default_value=message, readonly=True,
)

And to make the display a little bit nicer, add this theme to the __init__():

# Makes the input background transparent in the child window
with dpg.theme() as bg_theme:
    with dpg.theme_component(0):
        dpg.add_theme_color(dpg.mvThemeCol_FrameBg, (0, 0, 0, 0))
dpg.bind_item_theme(self.child_id, bg_theme)

This allows keeping the very useful filtering option but won’t allow multiline selection.

Could make a PR if @hoffstadt is ok with this approach.

My previous attempt does not display multiline messages correctly.

Another approach is to use a button which copies the message to the clipboard:

new_log = dpg.add_button(
    label=message,
    parent=self.filter_id, filter_key=message,
    user_data=message, callback=lambda s, a, u: dpg.set_clipboard_text(u))
with dpg.tooltip(dpg.last_item()):
    dpg.add_text("Press to copy to clipboard")

Still hacky but could prove useful.

I'm not using DearPyGui-Ext, rather, just DearPyGui, but I believe this could still be useful to someone.

To achieve multiline selection and visual coherence, I just created a single input_text that looks like this inside of the relevant window:

    dpg.add_input_text(
        tag="rcon_out",
        parent="command_line_output",
        multiline=True,
        readonly=True,
        auto_select_all=True
    )

Then I just update it with set_value() by taking the current value with get_value() and appending the new data:

    dpg.set_value("rcon_out", dpg.get_value("rcon_out") + '\n' + data)

How I'm appending the data and what that looks like is obviously dependent on what you're doing, but overall this method works for me.
