all: partially migrate to math/rand/v2
...
This is not intended to be a completed transition since it leaves the
libraries unusable to external client code, but rather as a step towards
use of math/rand/v2. This initial step allows repair of sequence change
failures without having to worry about API difference.

mat: calculate Q elements lazily when calling QR.At
...
When a matrix is very tall, calculating Q will currently allocate a
large Q at the end of the factorisation, even if it is not going to be
used, and a large Q matrix can lead to out of memory issues.
For this reason, Q is never eagerly computed unless explicitly required
to by the user, with QR.ToQ.
To keep fulfilling the Matrix interface, the QR.At method will compute
the requested element only, which only require computing a single row of
Q.

mat: fix dst matrix shape check in QR.RTo

Fixed a typo in row/column size check, the
expected row size was incorrectly checked against
the column size.
