enforce bundle limits when exploding file enumerations

[aronatkins]

The rsconnect.max.bundle.size and rsconnect.max.bundle.files limits are enforced both with appFiles as well as without appFiles. Previously, we would not enforce limits when appFiles or appFileManifest was given.

options(rsconnect.max.bundle.size = 10)
rsconnect::deployApp(server = "SERVER", account = "ACCOUNT", appFiles=c("app.R"))
#> Error: The directory DIRECTORY cannot be deployed because it is too large (the maximum size is 10 bytes). Remove some files or adjust the rsconnect.max.bundle.size option.

options(rsconnect.max.bundle.size = 10)
rsconnect::deployApp(server = "SERVER", account = "ACCOUNT")
#> Error: The directory DIRECTORY cannot be deployed because it is too large (the maximum size is 10 bytes). Remove some files or adjust the rsconnect.max.bundle.size option.

Testing notes:

• Make sure we enforce the limit however we upload (push button, modify the files, directly deploy app, deploy in R in different ways and make sure we enforce the limit)
