Change Merkle tree library to use ReaderAt
Merkle tree library was originally using Read/Seek to access data and
tree, since the parameters are io.ReadSeeker. This could cause race
conditions if multiple threads accesses the same fd to read. Here we
change to use ReaderAt, and implement it with PRead to make it thread
safe.
