Add Volume Controller

[DiegoxK]

This pull request addresses issue #4 by adding a volume control feature to the extension. Users can now adjust the volume of the voice lines played by the extension.

First off, thank you for these PRs! This comment addresses both #13 and #14.

The code updates seem fine at first glance, however before taking a closer look I would like to ask you to fix the formating. Notice that a lot of extra lines has been changed (see the diff) due to whitespace changes.
I would also like you to change the defaults to align with the current behaviour, set default volume to 1.0, and default delay to exactly 0 ms.

Got it, i forgot to deactivate the default usage of prettier and that formatted all the files by default, sorry.
Let me work on it

Okay, I believe this branch now only includes the necessary changes made to Player.ts and package.json, along with a default volume of 1.

Have you tested these changes?

Can you also commit the package-lock.json file. This will help when building in the future.

I have tested the changes, and setting the volume to values above 15 produces very loud sounds, while setting a volume of 0.01 produces very low sounds, which is working as expected.

Great! Because I can't get it to install on my PC right now (some npm issue), but I'll trust you that it works 👍

Great work! Thank you!
