[Buildroot] [git commit] package/signal-estimator: add new package

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=e3b2bc21d52fc949ac62964bc4c628c5143e4954
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

We need to use the git download mechanism, as the package depends on a
submodule (an old version of cxxopt), and this is not included in the
archive autogenerated by Github.
