Routes are not ignoring .DS_Store files and build breaks

[arxpoetica]

Sneer: why, Apple. Why.

This change 93128a0 introduced the problem. The build breaks when those sometimes autogenerated Apple files appear. I'm wondering what other . files will cause problems?

[Rich-Harris]

Proposed fix: exclude files without an extension. I can't think of any common dotfiles that have one, and all your route files will have one (whether .js, .html, .ts or something else).

Would be an easy PR if anyone wants to take it one — src here, tests here

@Rich-Harris that would break .well-known, wasn't this the reason this was introduced in the first place?

#243

I searched the Internet for information about .DS_Store issue (because I'm not a macOS user.) I agree ignoring files with . prefix is the best solution.
#254 ignores those files except .well-known, which #243 allowed to implement as @silentworks points out.

@Rich-Harris good on ya' for pointing us in the way to fix it instead of just doing it. ;)

If you keep up that pattern, I'll definitely try and jump in the game more.
