atime_versions() works with package in sub-dir of git repo

[tdhock]

Closes #79

example code:

remotes::install_github("tdhock/atime@pkg-subdir")
gdir <- tempfile()
dir.create(gdir)
git2r::clone("https://github.com/tdhock/grates", gdir)
glist <- atime::atime_versions(
  file.path(gdir,"pkg"),
  current = "1aae646888dcedb128c9076d9bd53fcb4075dcda",
  old     = "51056b9c4363797023da4572bde07e345ce57d9c",
  setup   = date_vec <- rep(Sys.Date(), N),
  expr    = grates::as_yearmonth(date_vec))
plot(glist)

I see this result
