fulltext v1.7.0

NEW FEATURES

• The Cross Text and Data Mining program has ended. It ended officially at the end of 2020, but it took Wiley until early February to implement a TDM service. This impacts ft_get only, and impacts retrieval of only Wiley and Elsevier works (which is a lot since they're very large publishers). You now have to get a TDM key from both Wiley and Elsevier. See the "Authentication" section in ?fulltext for details. See also ?"ft_get-warnings": there's a new warning if we detect that you have a CROSSREF_TDM env var (#224)
• Added new ft_get plugin for Trans Tech Publications (#232)
• Import dependency crminer dropped. A few crminer functions brought over into this package and renamed. This is due to Crossref TDM program ending (#233)

MINOR IMPROVEMENTS

• new ft_search() docs section "Pagination" describing what parameter names to use for each data source to do pagination

BUG FIXES

• ft_search() fix: some data source specific options (e.g., plosopts) were being overridden by the global equivalent options (e.g., in ft_search(limit = 5, from = c("plos", "entrez"), plosopts = list(limit=10)) the limit sent to PLOS was 5 instead of 10). Fixed now so that data source specfiic options override the matching global option (#229)
• Internal API Fatcat changed its parameter name to limit what fields are returned. Fixed now (#231)
