fix: mouse buttons

[Riverlance]

Description

Mouse buttons uses bitwise logic, so these values should be like 0, 1, 2, 4, 8, and so on, not like 0, 1, 2, 3, 4, 5, 6, 7, 8, and so on.

Behaviour

Actual

As an example, MouseMidButton was the same as pressing MouseLeftButton + MouseRightButton at the same time. Because MouseLeftButton (1) + MouseRightButton (2) = MouseMidButton (3). It means, if I check in my code if I'm pressing mid button g_window.isPressed(MouseMidButton), it will work with mid button, but ALSO if I click left+right buttons.

Expected

If I check like g_window.isPressed(MouseMidButton), it should not consider this as true if I click left+right buttons.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested

1. Use the code below somewhere:

print(g_window.isPressed(MouseMidButton))

2. Then press left+right buttons. It will print true, but it should be false instead, since you are not pressing the mid button.

unfortunately it cannot be like that, the 'left shift(<<)' has to be applied only to m_mouseButtonStates, because when I click, for example, on the number 4 of the mouse, it returns 8.

middle returned 4
