Dont fail on wheels without Requires-Dist lines

[DBS-ST-VIT]

This is a fix that solves the problem, that was described in #20

Thanks for the report and fix! Appreciate the no-deps test package - I'm inclined to say that it's not worth freezing a wheel with no dependencies, but that also shouldn't break.

A couple suggestions inline, not critical.

Good catch here! Though I think if we don't have any dependencies to freeze, we can probably avoid calling replace_deps() in the first place by making a change later in the file:

@@ -296,7 +295,8 @@ class IcedPoet:
             deps = self.get_path_deps(MAIN_GROUP)
             deps.update(dep_packages)
             dep_lines = self.get_frozen_deps(deps, self.exclude_packages)
-            self.replace_deps(dist_meta, dep_lines)
+            if dep_lines:
+                self.replace_deps(dist_meta, dep_lines)
 
             with source_whl.open(record_path) as record_fh:
                 record_text = self.freeze_record(record_fh, dist_meta, md_path)

It's still a good call to play it safe and avoid the chance for a None here, but we should still be able to cover that without indenting all of this logic:

Suggested change

	requires_dist = dist_meta.get_all("Requires-Dist")
	if requires_dist:
	for m in requires_dist:
	if not start_pos:
	start_pos = dist_meta._headers.index(("Requires-Dist", m))
	dist_meta._headers.remove(("Requires-Dist", m))
	for idx, h in enumerate(dep_lines):
	dist_meta._headers.insert(start_pos + idx, ("Requires-Dist", h))
	for m in dist_meta.get_all("Requires-Dist", ()):
	if not start_pos:
	start_pos = dist_meta._headers.index(("Requires-Dist", m))
	dist_meta._headers.remove(("Requires-Dist", m))
	for idx, h in enumerate(dep_lines):
	dist_meta._headers.insert(start_pos + idx, ("Requires-Dist", h))

Good Morning and thanks for your quick response!
I absolutely agree with your suggestions, which is why i added them already into my PR.

I'm inclined to say that it's not worth freezing a wheel with no dependencies, but that also shouldn't break.

Of course - i absolutely understand that point. But we are facing a edge case on our side - theres a pipeline template which is executing poetry build and poetry freeze-wheel for all of our python projects. Of course, we can put the logic also into the pipeline with some greping and if-conditions, which actually looked very hacky to us - thats the reason, why we decided to contribute the fix into this project. :)

Tests are failing here due to code coverage upload failures. I'll get a separate PR together for that, we've had success in other projects moving from a manual upload to a supported GitHub action.

Heyho @ajkerrigan ,
are there any news regarding to this PR/the mentioned CI problems?
