Improvements aiming at continuing the expansion of the support of different Ocean Optics spectrometers and of additional measurement methods.
Update acq_irrad_interactive() adding alternative user-interface modes, allowing users to set comment and what.measured attributes, and to construct collections of spectra.
Add pre-built calibrations and methods for additional FLAME-S instruments.
Improve algorithm for automatic tuning of integration time to achieve faster convergence.
Fix various minor bugs.
Test against OmniDriver 1.2.56
Update read_ooov_files() for compatibility with ‘readr’ >= 1.2.0 which is now required
Add support for measurement of pulsed light sources (under development)
The new features described below are under development, subject to change without previous notice and not yet well tested!! (double-check any results and please report any bugs by raising an issue!)
Implement support for measuring output from xenon flashes, including use of such flashes as light sources for measurement of spectral transmittance and reflectance. Use of multiple exposures per integration is also supported and the number of exposures stored as metadata is used during later processing. In the case of pulsed light sources the first conversion of RAW spectra is into counts per exposure, and instead of spectral irradiance spectral fluence per exposure is computed. All changes are backwards compatible with raw data acquired with earlier versions of ‘ooacquire’ and the user interface remains unaltered for the measurement of continuous light sources.
Add function acq_fluence_interactive() for measuring spectral fluence of pulsed light sources.
Add acq_fraction_pulsed_interactive() for measuring transmittance and reflectance using a pulsed light source.

The main changes from version0.4.17-1 the previous CRAN release, are:
Track code breaking change in ‘readr’ (>= 1.2.0)
Fix bug in read_oo_pidata() that was preventing reading of Ocean Optics “Raspberry Pi” Flame files with a sequence header line at the top.
Add decoding of file header to extract integration time and number of scans to read_oo_pidata().
Improve decoding of file header to extract instrument settings in read_oo_jazdata().
Because of code breaking change in package ‘readr’ this version of ‘photobiologyInOut’ requires ‘readr’ >= 1.2.0 to be installed. Function read_oopi_data() from ‘photobiologyInOut’ < 0.4.18 will not work as expected under ‘readr’ >= 1.2.0. (I thank Jim Hester for making a pull request that solved the problem introduced by the change in ‘readr’.
