simfinapi 0.2.0

Possibly Breaking Changes

All column names in returned data.tables now comply to basic naming conventions. The original column names are stored in the label attribute of each column.

Added a NEWS.md file to track changes to the package.
Clean support for SimFin+. Most functions throw early errors if a normal user requests data which is reserved for SimFin+ users. If SimFin+ offers only more convenience, this is matched internally for normal users so that the user experience is very similar. Normal users only need more requests and therefore have to wait a little longer. However, this requires for most functions the new argument sfplus.
sfa_get_*() functions now feature a progress bar powered by {progressr} for normal users since simfinapi sends possibly many requests.

set_sfa_cache_dir() is now exported.
Corrections in sfa_get_shares() help.
The ratios argument in sfa_get_prices() is no longer ignored.
It’s now possible to download statement data for several years at once (if you are a ‘SimFin+’ user).
It’s now possible to download “all” statements at once (if you are a ‘SimFin+’ user). Some column names occur in several statements and duplicates are numbered with _2.
Argument fyear from sfa_get_statement() no longer has a default value. This prevents errors for SimFin+ users, who set start or end. (#13, reported by MislavSag)
Too strict input checks on Ticker and SimfinId removed. (#15, reported by MislavSag)
