Update geometry generation functions

See merge request in-nova/in-nova!5

Combine offset input arguments to a single translation vector and change variable name for the rotation/orientation of the geometries

Combine offset input arguments to a single translation vector and skip checks for translation of geometries

Change the example in Virtual Sensing README.md after changes in virtMicGeo.m and added newline to separate the references correctly

Fix time-domain calculations of the optimal observation filter

Closes #8

See merge request in-nova/in-nova!4

Remove scaling from cross-correlations and reshape observation filters with single liners instead of loops in obsFiltTD.m

Update to v0.2.3

See merge request in-nova/in-nova!3

Separate the source strengths and signal length input arguments, updated input argument checks and source signal calculations

Fixed errors in header documentation, fixed calculations of mean O to be calculated by averaged Rme and Rmm and introduced separate (fractional) delays for each virtual microphone in either samples or seconds

Update project README.md to included info on latest Sound Field additions and some of the old functions added in 0.2.0 and corrected a typo at the top of the file
