Feature Request: Shift (hold key) to run/sprint

[iwanPlays]

What
Add option to press shift to run in addition to W-tap.

Why
Receiver 2 has it, https://steamcommunity.com/app/1129310/discussions/search/?q=shift+run&gidforum=2865909887923510527&include_deleted=1

For me personally the worst part about it is not being able to fine-jump onto ledges, as tapping w makes me leap over into death.

Turning on shift/hold-sprint should at the same time disable tap-sprint.

Alternatives
I've been hacking the game with dnspy for my need but I'd be nice to have for accessibility.
Others use AHK scripts or something.

How

R1 ui suggestion:

Ideally "toggleable sprint" would be disabled if "holdable sprint" is disabled but even R2 doesn't have that, so...

Code findings

From discord:

- Find if(old_vert_axis < 0.9f && character_input.GetAxis("Vertical") >= 0.9f){
- Replace with if(Input.GetKey(KeyCode.LeftShift) || old_vert_axis < 0.9f && character_input.GetAxis("Vertical") >= 0.9f){

but then

if((Input.GetKey(KeyCode.LeftShift) && character_input.GetAxis("Vertical") >= 0.9f) || (old_vert_axis < 0.9f && character_input.GetAxis("Vertical") >= 0.9f)){
Would do that instead

and also

if (true)
{
    if (!this.crouching && Input.GetKey(KeyCode.LeftShift) && !base.GetComponent<AimScript>().IsAiming())
    {
        this.SetRunning(Mathf.Clamp(2f, 0.01f, 1f));
        this.bool_running = true;
    }
    this.forward_input_delay = 0f;
}
this.forward_input_delay += Time.deltaTime;
if (!Input.GetKey(KeyCode.LeftShift) || base.GetComponent<AimScript>().IsAiming())
{
    this.SetRunning(0f);
    this.bool_running = false;
}

I was told that MovementInputs.cs gets auto-updated after modifying MovementInputs.inputactions, so there would be no need to manually edit it.

Would be cool if someone was up to the task but worst case I'll come back with more free time in a year and try to make a commit based on these notes :)
