Due to too many breaking changes, i decided to raise the package version to 2.0.0

Changes #

• Changed invokeMacroList function name to invokeKeys
• invokeKeys will now take a list of KeyRecording instead of a List of logicalKeyboardKeys, so logicalKeyboardKeysToMacro is no longer needed, and got removed.
• All recorder-related functions have been moved into a dedicated KeyboardRecorder class, which is now accessible as the recorder property of the KeyboardInvoker class.
• Added KeyMap enum to represent the key mapping, instead of using the flutter logical key ids. The KeyMap enum can return the BaseKey and the KeyRecording for each key inside the enum.
• Added BaseKeyMap class to map the logical keys to the BaseKey classes.
• Added KeyRecordingsMap class to convert a list of LogicalKeyboardKey to a list of KeyRecording.
• Added KeyRecording class to represent a key recording, which includes the logical key id, description, and delay.
• Added KeyEventType enum to represent the type of key event (keyDown, keyUp, keyInvoke).
• Updated the example app.

• Initial release.
