hidecan 1.2.0.9000

In hidecan_aes() the default point shape for QTL regions is now 24. It was previously NA which would cause the regions to not appear in the plot when setting show_as_rect to FALSE for the QTL tracks.

hidecan 1.2.0

New S3 classes to store QTL regions: QTL_data and QTL_data_thr.
hidecan_plot() now has arguments qtl_list (to pass a list of QTL mapping results) and score_thr_qtl (to set the significance threshold on the score of QTL regions). The significant QTL regions are represented as rectangles spanning the length of the region on the tracks.

New S3 classes to store custom genomic features: CUSTOM_data and CUSTOM_data_thr, which can be represented either as genomic locations (points) or regions (rectangles).
create_hidecan_plot() now accepts CUSTOM_data_thr objects as input, which allows users to add custom tracks to their plot. It has an additional argument custom_aes to handle the aesthetics for custom tracks.
Added the hidecan_aes() function which returns the default aesthetics for the different types of data in the plot.

Added the manhattan_plot() function to generate Manhattan plots from a table of GWAS results.
Fixed bug where specifying chromosome limits for hidecan_plot_from_gwaspoly() would mess up the ordering of the chromosomes in the plot.

Removed get_gwaspoly_example_data() function so that the package doesn't depend on GWASpoly (for CRAN submission)
Saved the example object previously returned by get_gwaspoly_example_data() in as an rda file in the extdata folder
