Creates a multiple sampler objects and sets parameters on each.

Example:

     const samplers = twgl.createSamplers(gl, {
       nearest: {
         minMag: gl.NEAREST,
       },
       nearestClampS: {
         minMag: gl.NEAREST,
         wrapS: gl.CLAMP_TO_NEAREST,
       },
       linear: {
         minMag: gl.LINEAR,
       },
       nearestClamp: {
         minMag: gl.NEAREST,
         wrap: gl.CLAMP_TO_EDGE,
       },
       linearClamp: {
         minMag: gl.LINEAR,
         wrap: gl.CLAMP_TO_EDGE,
       },
       linearClampT: {
         minMag: gl.LINEAR,
         wrapT: gl.CLAMP_TO_EDGE,
       },
     });
