Need a way to allow/ignore directories

[smoelius]

build-wrap supports an allow.txt configuration file, which effectively disables build-wrap for a dependency:
https://github.com/trailofbits/build-wrap?tab=readme-ov-file#homeconfigbuild-wrapallowtxt

However, this has turned out to be not convenient enough. From my own experience, I often don't want to figure out which dependency is causing build-wrap to fail. So I disable build-wrap altogether and then forget to reenable it. A better solution would allow build-wrap to be disabled for a directory rather than system wide.

So I am proposing to create a $HOME/.config/build-wrap/config.toml file, which would take precedence over allow.txt.

The new file would contain entries like this:

[allow]
directories = ["..."]
packages = ["..."]

Or this:

[ignore]
directories = ["..."]
packages = ["..."]

The reason for both [allow] and [ignore] is that I cannot decide which I prefer.

Note that I am currently going with "packages" over "dependencies" because one might expect the latter to include versions, e.g., svm-rs-builds@0.5.18. Perhaps this could be a future enhancement.
