zx::result<size_t> CalculateMerkleTreeSize (size_t data_size, size_t node_size, bool use_compact_format)
```
Convenience method for calculating the minimum size needed to hold a Merkle tree for the given

|data_size|. It does NOT include room for the root digest.

Returns ZX_ERR_INVALID_ARGS if |node_size| does not satisfy |NodeDigest::IsValidNodeSize|.

|use_compact_format| specifies if the size should not include padding in the hash lists.

Returns ZX_ERR_OUT_OF_RANGE on overflow.
