Add back readUnsignedLeb128 in ClickHouseRowBinaryInputStream #710
Description
When using the ClickHouseRowBinaryInputStream we used to be able to manually read string, arrays, etc by calling readUnsignedLeb128 to get the length and then iterating through the elements. It was removed with version 0.3.0 (commit# 074a030). See here for the change. Since the ClickHouseRowBinaryInputStream class interacts with the private instance of DataInputStream there is no current access to the information.
The following code could be added back.
public int readUnsignedLeb128() throws IOException {
return Utils.readUnsignedLeb128(in);
}
