Remove unimplemented internal functions.

[noughtmare]

Running cabal test fails because the linker can't find these functions:

In Image.hsc:

• af_iterative_deconv
• af_iverse_deconv

In LAPACK.hsc:

• af_pinverse

In Signal.hsc:

• af_approx1_uniform
• af_approx2_uniform

Should these functions be removed?

@noughtmare can you confirm you're using 3.6.4. If so, then yes I can make a PR to comment them out. They might have been implemented from building off of master.

@dmjio Yes, I'm using 3.6.4. Interestingly, there are some comments in the higher level *.hs files about this:

arrayfire-haskell/src/ArrayFire/LAPACK.hs

Line 198 in 65bdf72

-- Not implemented in /3.6.4/

and

arrayfire-haskell/src/ArrayFire/Signal.hs

Line 561 in 65bdf72

-- DMJ: did this get removed? Can't find in latest docs

fftConvolve1 was commented out. I'll update the others as well. Thanks for looking into this.
