chromatograph 0.4.4

*Fixed issue with tests when run on certain machines (MKL).

chromatograph 0.4.3

Added option to select time.units for peak area in get_peaks function facilitating better comparison with vendor software.
Now allow preservation of instrumental metadata through pre-processing and alignment steps.
Added filter_peaktable function.
Changed default behavior in correct_rt to corrected_values rather than models.
Fixed bug in cluster_spectra affecting peaks with 0 standard deviation.
Fixed bug affecting peak_list metadata.
Deprecated load_chroms function. Please use read_chroms from chromConverter to import files instead.

Added more informative warnings and error messages to various functions.
Now recommend installation of VPdtw from CRAN instead of https://ethanbass.github.io/drat/
Fixed typos in vignette

Extended package DESCRIPTION and added citations to relevant references.
Added \value and \section{Side effects} fields to docs for the various plot functions.
Fixed bug in mirror_plot so legend can be fully hidden by setting plot_legend to FALSE.
Fixed bug in scan_chrom so additional arguments are passed to plot_spectrum.
Added color argument to customize color of fitted peaks in plot.peak_list.
Fixed plot functions and examples so they don’t change par settings.
Other small updates to documents (mostly formatting or small clarifications).
Fixed plot.peak_table so it can return spectra if export_spectrum is TRUE.
Added error for box_plot option in plot.peak_table if metadata is not attached.
Added error for box_plot option in plot.peak_table if peak is not provided to loc.
Added error in plot_spectrum function for user-supplied retention times beyond the edges of the chromatogram.
Added error in plot_spectrum function for unspecified lambda (if what=="click).
Released on CRAN

Added support for variable penalty dynamic time warping (VPdtw) through correct_rt function.
Fixed bug in get_peaks function.
Allow preprocessing without interpolation.
Fixed bug so preprocess can work on Windows (without parallel processing).
Allow use of raw data for peak integration in get_peaks.
Added verbose option to correct_rt to print reference chromatogram.
