 * Exports a `createHelia` function that returns an object that implements the {@link Helia} API.
 *
 * Pass it to other modules like {@link https://www.npmjs.com/package/@helia/unixfs | @helia/unixfs} to make files available on the distributed web.
 *
 * @example
 *
 * ```typescript
 * import { createHelia } from 'helia'
 * import { unixfs } from '@helia/unixfs'
 * import { CID } from 'multiformats/cid'
 *
 * const helia = await createHelia()
 *
 * const fs = unixfs(helia)
 * fs.cat(CID.parse('bafyFoo'))
 * ```
