[IPFS upload Fix]: Use Buffer object for NodeJs environment

[nicolapertosa]

Description

I could found a solution by using a Buffer object when we try to use "nftIpfsUpload" and "collectionIpfsUpload" utils in NodeJs.

What I do :

• I check if the File & Blob objects are available, if not I assume we are in a NodeJs environment.
• If in a browser environment, I'm still using File & Blob and pass File object to "ipfsFileUpload" helper.
• If in a NodeJs environment, I use Uint8Array instead of Blob and Buffer instead of File objects.

The "isBrowser" variable could rely on something else and can also be externalised in the helpers part. Of course, I'm still open to discuss which solution you prefer.
