feat: add /rgbpp/v1/assets/type for get assets type info

[ahonn]

Add an new API /rgbpp/v1/assets/type to get asset cell type info (xUDT and Spore for now)

Interface

// /rgbpp/v1/assets/type

// query params
{
    querystring: z.object({
    type_script: Script.or(z.string())
      .optional()
      .describe(
        `
        type script to filter cells

        two ways to provide:
        - as a object: 'encodeURIComponent(JSON.stringify({"codeHash":"0x...", "args":"0x...", "hashType":"type"}))'
        - as a hex string: '0x...' (You can pack by @ckb-lumos/codec blockchain.Script.pack({ "codeHash": "0x...", ... }))
      `,
      ),
  }),
}

// response
z.object({
  type: z.literal('xudt')
  symbol: z.string(),
  name: z.string(),
  decimal: z.number(),
  type_hash: z.string(),
}).or(z.object({
  type: z.literal('spore')
  contentType: z.string(),
  cluster: z.object({
    id: z.string(),
    name: z.string(),
    description: z.string(),
  }).optional(),
})).nullable();
