row_size and column_size are nil

https://github.com/willcannings/Ruby-SVD/blob/master/lib/svd_matrix.rb#L41

Here, values of row_size and column_size are nil. Due to this SVD is throwing error:

TypeError: no implicit conversion from nil to integer

@naveenkumarjtg I published ruby-esvidi because I had the same error plus other ones and without commits in this project from 7 years ago and no commits from willcannings in the last year I don't think we will have an answer.
