New Features

Added example of fitSpectraSMC with informative priors to the methanol vignette.

Removed the R package hyperSpec from Suggests because it is no longer available on CRAN.
Fixed dependency on hyperSpec in Introduction vignette due to new CRAN check. This also affects the TAMRA dataset.
Fixed a rare bug in reweighting that could potentially result in an infinite loop.
Peak locations are now constrained to lie within the range of observed wavelengths.
Locations are sorted to preserve identifiability.
Fixed error in equations for FWHM in mixedVoigt & getVoigtParam as well as in both vignettes.

OpenMP implementation of mhUpdateVoigt provides around 3x improvement in elapsed runtime
New vignette illustrates when to use the 3 functions fitSpectraMCMC, fitSpectraSMC, and fitVoigtPeaksSMC
New datasets methanol and TAMRA for use in the vignettes
Debug output prints the means of the amplitudes of the peaks at each SMC iteration

Fixed bug in fitVoigtPeaksSMC where it was using the upper-triangular instead of lower-triangular Cholesky factorisation to generate random-walk Metropolis proposals
Introduction vignette no longer attempts to download a .zip file over HTTPS
Deleted unused Rcpp function randomWalkVoigt
