tsl transpiler dont recognize 8U

[Makio64]

Description

While transpiling this code i discover the 8U isnt correctly understand by the transpiler.

Reproduction steps

In tsl transpiler :

8U ->int( 8U )
expected
8U -> uint( 8 )

also in the following example it seems the mul of x as uvec3 by uint not working correctly

// hash33 by iq https://www.shadertoy.com/view/XlXcW4
const uint k = 1103515245U;  // GLIB C

vec3 hash33( uvec3 x )
{
    x = ((x>>8U)^x.yzx)*k;
    x = ((x>>8U)^x.yzx)*k;
    x = ((x>>8U)^x.yzx)*k;
    
    return vec3(x)*(1.0/float(0xffffffffU));
}

result :

// Three.js Transpiler r172

import { int, uint, uvec3, vec3, float, div, Fn } from 'three/tsl';

const k = uint( int( 1103515245U ) );

export const hash33 = /*#__PURE__*/ Fn( ( [ x_immutable ] ) => {

	const x = uvec3( x_immutable ).toVar();
	x.assign( x.shiftRight( int( 8U ) ).bitXor( x.yzx ).mul( k ) );
	x.assign( x.shiftRight( int( 8U ) ).bitXor( x.yzx ).mul( k ) );
	x.assign( x.shiftRight( int( 8U ) ).bitXor( x.yzx ).mul( k ) );

	return vec3( x ).mul( div( 1.0, float( int( 0xffffffffU ) ) ) );

} ).setLayout( {
	name: 'hash33',
	type: 'vec3',
	inputs: [
		{ name: 'x', type: 'uvec3' }
	]
} );
