add repo branch to reproducibility table

[mariev]

problemadding the branch of install to the reproducibility table will allow for quick visual verification that input data is from a "release from use status" i.e. installed from the main trunk. Currently it is not possible to determine this without exhaustive examination of the report code.

proposed solution add value from package DESCRIPTION RemoteRef to the $packages_table output from VISCfunctions::get_session_info() as an additional variable. This value can be obtained via packageDescription(PACKAGE_NAME)$RemoteRef

sample code:

(my_session_info2 %>%
    filter(str_detect(source, pattern = "git2r")) %>%
    pull(package) %>%
    packageDescription())[c("Package", "DataVersion", "RemoteRef", "RemoteSha")] %>%
as_tibble()
