Some tests are failing, below is given log

# the function supports a negative `stride` parameter
not ok 9 returns expected value
  ---
    operator: equal
    expected: 5
    actual:   0
    at: Test.test (/home/pranavchiku/stdlib/lib/node_modules/@stdlib/blas/base/snrm2/test/test.ndarray.native.js:124:4)
  ...

I am not sure why it is happening, @kgryte if you can have a look.

@Pranavchiku The test failures are due to your having removed the logic for ensuring that the stride is positive: https://github.com/stdlib-js/stdlib/pull/800/files#diff-a0af2215d328eb25f7e66afb3ee4a6b38e251a677a27096c8efb6fe1bbedbf92L50. The reference BLAS implementation does not support negative strides. So for the ndarray API (which does support negative strides), we need to convert to positive before passing down to C.

Okay, I will have a look asap.

@Pranavchiku LMK once this PR has been updated, and I'll take another look.
