Pass R CMD check with no errors

[mhpob]

R CMD check should complete without errors (only warnings!) after review/acceptance of this.

List of changes:

• R CMD check GitHub Action only fails if ERRORs are found. Should later be changed to WARNINGs as those are addressed (can't have ERRORs or WARNINGs to be on CRAN)
• Fixes the "There are ::: calls to the package's namespace in its code. A package almost never needs to use ::: for its own objects" warning in R CMD check.
• Since the internal namespace references are removed, a developer should "load all" to have access to internal functions (devtools::load_all)
• Add util-intern_pkg_man.R to Rbuildignore to remove dependency on usethis
• Add undeclared dependency on units
• Moved knitr, rmarkdown, and methods to Suggests to reduce direct dependencies
• fasttime dependency has been removed. Documentation still needs to be updated
• Uses \dontrun to skip examples that won't work until fix for #202
• Uses \dontrun to skip examples needing vdat.exe
• Fixes broken examples in make_transition3 and kml_to_csv
• Uses try to catch and print the example error in examples for glatos_detections, glatos_receivers, and glatos_animals
• Changes and T or F in the examples to TRUE or FALSE since R CMD check is apparently extremely opinionated

@jdpye could I ask you (or anyone else) to run devtools::document or roxygen2::roxygenize on this PR and commit? I have a weird system specific thing preventing me from doing so.

It should fix the last R CMD check error... Or let it progress down the line to the next error it hasn't gotten to yet.

I'll give it a shot today, yep!

Mike, I think you won out!

@chrisholbrook @jdpye I hope you weren't getting hammered with all of those notices, but if you were...

GLATOS NOW PASSES R CMD CHECK!

(ish. Warnings still need to be addressed, but now if we don't get the pretty green check marks after a commit you know that something is probably not good.)

GLATOS NOW PASSES R CMD CHECK!

@mhpob Wow! Can't thank you enough for incredible mop up effort here! also @jdpye for keeping momentum.

Confirming as of now (https://github.com/ocean-tracking-network/glatos/commit/f016ab1538634e6368da7b80411046d2251ef253) passes devtools::check() for me locally:
