Big blob and icrc7 nft

Not sure to understand,
ic_certified_assets has not been updated since 2 years now, and on this topics : Announcing the HTTP certification library for Rust - #14 by unixway Severin said it’s not up to date anymore and we should use ic-asset-certification, which is not yet released AFAIK.

looks like this part is currently been reworked, right ?
Basicly what i’m looking for is the crate to handle the upload/get of the (potential big) file to a specific canister, ideally compatible with icx-asset (and a js lib) so we dont have to re-invent the wheel.

Thanks !
