`renv_lock_pkgs()` provides the basic functionality of getting the list
of R packages present in an renv.lock file.
It does NOT handle the versions of those packages or transitive
dependencies not directly used in the project.

---

`renv_lock_r_ver()` retrieves the R version from an renv.lock file.

---

adds the `exclude_other_sources` option to `renv_lock_pkgs()` and
defaults it to TRUE.
This excludes packages from being returned if the do not have
"Repository" as their value for "Source" in renv.lock the and throws a
warning listing the excluded packages.
This should exclude packages from sources like github which are not
presently like to be packaged in nix.

---

add `renv2nix()` wraps `rix()` and populates `r_ver`, `r_pkgs`,
`git_pkgs`, and `local_r_pkgs` based on an `renv.lock` file.

---

The `return_rix_call` argument allows `renv2rix()` to return the call to
the rix function instead of evaluating it, this allows or debugging the
call.

…` information

---

The `renv_remote_pkgs()` function takes a single renv.lock package entry
as an argument, infers it's remote type and extracts the informaton
necesary for `rix()`'s `git_pkgs` argument.

This functionality was factored out of the `renv2nix()`, and the
`method` argument added `renv2nix()` to allow for a future
implementation of exact package version matching.

…d option

---

Returns a list of package information suitable to supply to the
`git_pkgs` argument of `rix()`

…ith type assertion handling

---

Ability to allow remote type inference with error for unsupported types
as well as to assert a remote type expected for all pkgs

simpler to work with than using logicals approach and fixes bug with NAs
in `r_pkgs` in the previous approach.

These files come from some random projects of mine sampled from those
generated with a few different versions of renv, and one which is a
snapshot of the current rix package.

if source was not "Repository" `renv2nix()` looked for a remote, source
can also be "Bioconductor" and not have a remote which resulted in an
error as remote was empty when source was "Bioconductor"
