IPV 0.2.0

Added Features

Package now works based on raw data with automated model estimation using lavaan (function ipv_est). This is now the recommended workflow!
New raw example data (HEXACO) from the open psychometrics project (see ?HEXACO).
Create an overview over all (squared) factor loadings in all three models on which a nested chart is based (function item_overview).
Refined method available to compute center distances for groups of items (parameter cd_method = "aggregate"). This is now the default method!
Show only a section of a chart (parameters zoom_x and zoom_y)
Convenient changing of test, facet, or item labels (function rename).
Rotate the tick label in facet charts and nested charts to avoid overlap (parameter rotate_tick_label).
Set the limit of the grid in item charts (parameter grid_limit).
Set the order of facets for all charts types (parameter facet_order).
Set the order of tests for nested charts (parameter test_order).
Add an overall title for all chart types (parameter title).
Draw xarrows in a nested chart that end on a test circle (instead of a facet circle) if facet1or facet2 is specified as NA for that arrow.
Overhaul of the documentation in the vignette.

Standardized the default order of facets across facet charts and item charts. It is now consistently the order of the correlation matrix columns in data =.
Negative correlations between facets or tests should now be displayed correctly.
Removed an erroneous message claiming that the axis tick was set automatically when it was set manually.
The axis tick mark (gray dotted circle) now disappears “behind” circles of facet charts and nested charts, instead of cutting through them.
the axis tick label (number) now more reliably appears close to the axis tick mark in facet charts and nested charts.
removed the argument show_xarrows in nested_chart, which only existed for technical reasons.
