useFbx composable and component for cientos

[alvarosabu]

Is your feature request related to a problem? Please describe. Since a potential user is interested in using TresJS to load FBX models and to be honest, along with Gltf is one of the most used formats let's add support for it

Describe the solution you'd like Same thing as useGLTFbut for fbx models

Suggested solution

import { useFBX } from '@tresjs/cientos'

const { scene } = await useFBX('/models/AkuAku.fbx')

or

<script setup lang="ts">
import { OrbitControls, FBXModel } from '@tresjs/cientos'
</script>
<template>
  <Suspense>
    <TresCanvas clear-color="#82DBC5" shadows alpha>
      <TresPerspectiveCamera :position="[11, 11, 11]" />
      <OrbitControls />
      <TresScene>
        <FBXModel path="/models/AkuAku.fbx" />
        <TresDirectionalLight :position="[-4, 8, 4]" :intensity="1.5" cast-shadow />
      </TresScene>
    </TresCanvas>
  </Suspense>
</template>

for the composable import the loader from three-stdlib
