App is able load a .gltf file using the opensea api

[truedat101]

Requirement:

• App has the means to input a contract address/token_id such (for now a UI input field)
• Use this api to fetch the JSON document https://docs.opensea.io/reference/retrieving-a-single-asset
• The opensea site has some NFTs with 3d objects that are browsable, for example: https://opensea.io/assets/0x3b3ee1931dc30c1957379fac9aba94d1c48a5405/69049
• Load the document from the API, and extract the animation_url from the asset
• retrieve the full GLTF object file and store into memory
• The asset should load asynchronously and should show progress on download
• if the asset fails to load present the appropriate error message in an alert dialog: (1) 404 (2) animation_url isn't available in the contract (3) network error
• Once the asset is in memory, load it into the gltf viewer created in #1

To see this as an example:

curl --request GET --url https://api.opensea.io/api/v1/asset/0x3b3ee1931dc30c1957379fac9aba94d1c48a5405/69049

Do this after #1

So we definitely want the animation_url.

I need to add a JSON parser .

So I'm just doing dirty old school dicts. That works ok.

This is all hardcoded in right now and it will get cleaned up once the NFC based tag reader is implemented.
