glydraw 0.4.1

Fix substituent annotations in glycan cartoons. (#16)
Fix reducing-end Fuc orientation in O-Fuc glycans. (#15)
Make export_cartoons() create the output directory when needed. (#17)
Make export_cartoons() use vector names as output filenames when available. (#17)

Add a highlight parameter to draw_cartoon(). (7e57a54, 3745ec8, c1057ba)
Add export_cartoons() to save multiple glycan structure cartoons to files. (e1ac3c3)

Fix the bug that reducing end annotation was not shown with unknown anomer information. (#12)
Fix the bug that glycans with only one monosaccharide could not be plotted. (#11)
Fix the bug that "?" in linkages was not correctly handled. (#9)
Fix the incorrect reducing end annotation direction in some situations. (#8)
Fix the bug that glycan structures with multiple branches had incorrect layouts. (2ac4e9f)
Fix the bug that "png" is not supported in save_cartoon(). (fed89b9)
Fix the bug that structures with generic "NeuAc" and "NeuGc" cannot be plotted. (3b78303)

Update dependency to glyrepr 0.10.0.
Fix various bugs including illegal character processing, fucose arrangement, and display sizing issues.

Now we use ggview instead of ggimage for size fixing, which relies on rstudioapi::viewer() to display the plot. You might feel some difference in the display effect, but the SNFG itself keeps the same.

Signature of draw_cartoon() is changed into draw_cartoon(structure, mono_size = 0.2, show_linkage = TRUE, orient = "H", ...) for better semantics.

draw_cartoon() now prints fixed-size cartoon (sizes are calculated based on glycan structures) to the plot panel, to provide a unified behavior with save_cartoon().
Add reducing end annotation to the cartoons (including a short segment and the anomer of the reducing end residue).

Update default aesthetic settings:
- Make residue size larger.
- Adjust linkage annotation positions.
- Add a border to the plot panel.
- Fix the issue that some linkage annotations are truncated.
Fix the bug that glycans with only one residue cannot be plotted by draw_cartoon().
Fix the bug that path parameter is mandatory in save_cartoon(). Now it is optional, to be in line with ggplot2::ggsave().
Update documentation of save_cartoon() to differentiate it with ggplot2::ggsave().
