Fetching BLOB (seg type 1) will only load the first 32078 bytes

[mreis1]

const blobStream = await attachment.openBlob(transaction, blob);

let len = await blobStream.length; 

If the MEMO stored is 32278 bytes, during the fetch it's "len" will be estimated to only 32078.

Looks like same reason than #36.
