restore sizecomp bootstrap output

[Rick-Methot-NOAA]

resolves issue #541

uses code that was created in issue #357 but accidentally deleted

Testing can use this zip, which may be a good candidate for adding to the test repo
D-M_test.zip

Testing demonstrates that data.expval and data.boot1 are different from data_echo.

I haven't gone through the equations in detail but am trusting that they were correct before being accidentally left out of the pull request.

I don't see the build-ss3 in the automatic checks for this PR (perhaps because changes were underway), but I found it under the Actions tab and downloaded the ss3-windows-latest archive from there, which worked fine: https://github.com/nmfs-ost/ss3-source-code/actions/runs/7265855922.

Running that new executable with the simple_small_sizecomp model attached to #539 resulted in reasonable-looking bootstrap size comp samples in data_boot_001.ss, precise expected values in data_exp.ss, and accurate input data in data_echo.ss_new.

The merge-base changed after approval.
