Subject: [PATCH] Use higher compute budget for helloworld sealevel (#2981)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

### Description

We need to request a higher compute limit for certain message indexes
that result in a higher # of internal nodes being hashed when inserting
into the merkle tree. Similar issue as #2771

### Drive-by changes

n/a

### Related issues

n/a

### Backward compatibility

yes

### Testing

none 😛
