tagtools 0.3.0

This release removes a dependency, speeds up filtering and decimation via C++, and fixes several bugs.

Breaking changes

m_dist() documentation clarified and input names changed to match rest of tagtools (all now snake case); unused inputs expStart and expEnd removed. To update old code, change input names: smoothDur to smooth_dur, cumSum to cum_sum, and baselineStart, baselineEnd, and BL_COV to baseline_start, baseline_end, and bl_cov.

read_cats()` now can now read deployments with multiple csv files.
dec_dc() now implements convolution via RCppArmadillo, which speeds it up.
gsignal package dependency replaces signal, for speed and flexibility.
prh_predictor1() and prh_predictor2() interactivity is now optional, toggled via a new input argument.

latex2exp package dependency removed, as requested by CRAN Team.
m_dist() documentation clarified and input names changed to match rest of tagtools (all now snake case); unused inputs expStart and expEnd removed. To update old code, change input names: smoothDur to smooth_dur, cumSum to cum_sum, and baselineStart, baselineEnd, and BL_COV to baseline_start, baseline_end, and bl_cov.
norm2() checks that output is a column vector (1-column matrix).
o2p() and read_cats() helper functions moved outside function definitions.
save_nc() now accepts dots input.
add_nc() works correctly even if sensor data stream name vname not input.

This release adds several new features and fixes several bugs.

plott() now generates interactive plots via the plotly package, and static ones via ggplot2. If you prefer base R graphics, the old implementation is still present at plott_base().
Changes to read_cats() mean it now changes all triaxial sensor data from the CATs standard right-handed NED axis orientation to the left-handed NEU one employed by the animaltags tagtools. If you employed custom code to make this change after reading in CATs data, the custom code will no longer be needed.
The col_line() function has been removed because its purpose is easily accomplished with ggplot2 (or other) graphics.

plott() now generates interactive plots via the plotly package, and static ones via ggplot2. If you prefer base R graphics, the old implementation is still present at plott_base(). plott() also now has an option to draw the plot, or instead return a list of graphics objects (one for each panel). This is helpful for users who would like to amend individual panels (for example, overlaying event times on a dive or flight profile).

read_cats() has been updated to deal better with the column names present in more recent CATs csv data files. It has also been amended to change all triaxial sensor data from the CATs standard right-handed NED axis orientation to the left-handed NEU one employed by the animaltags tagtools.
