Final switch to IMASDD

[anchal-physics]

This PR would be merged simultaneously when all other repos also have the PR ready for the final switch from OMAS to IMASDD.

• PR for GGDUtils.jl Final switch to IMASDD IMASggd.jl#41
• PR for SOLPS2IMAS.jl Final switch to IMASDD  SOLPS2imas.jl#32
• PR for SynthDiag.jl Final switch to IMASDD #26
• PR for SD4SOLPS.jl Final switch to IMASDD SOLPS2ctrl.jl#51

Speed test

I ran a speed test to check the difference between using OMAS and IMASDD. With IMASDD, add_inteferometer is 10 times slower. Interestingly, add_langmuir_probe is marginally faster. We'll need to find bottleneck in this repo as well. Following are the results:

Speed test with IMASDD.jl

Note that the warning is due to outdated sample file which is being read by IMASDD. I'll fix this sample file soon.

Inteferometer operation has been sped up by optimizing \in operation for point in a subset in GGDUtils at ProjectTorreyPines/IMASggd.jl@392b428

Now speed test results are:

SynthDiag.jl % julia --project test/speedtest.jl
-----------------------------------------------------------------------------
add_interferometer!() time with compilation:   9.951131 seconds (50.11 M allocations: 4.110 GiB, 5.75% gc time, 48.21% compilation time)
add_interferometer!() time (true runtime):   5.389749 seconds (35.12 M allocations: 3.124 GiB, 4.63% gc time)
-----------------------------------------------------------------------------
add_langmuir_probes!() time with compilation:   3.002231 seconds (7.34 M allocations: 694.869 MiB, 2.85% gc time, 62.67% compilation time)
add_langmuir_probes!() time (true runtime):   0.983486 seconds (220.36 k allocations: 196.590 MiB)

This is almost the same performance as when OMAS was used. So now we can consider this PR ready for merge as well.

I'll wait for #25 to be accepted before submitting this PR for review. I'll rebase with dev and see if gas_injection also requires any optimization with IMASDD.

[anchal-physics]

I have rebased to incorporate #25 . A speedtest has been added for gas_injection functions too and it looks fine.

This PR is ready for merge now. I'll submit all four PRs for review.
