Any possibility of .NET 4.6.2 support?

@mtkennerly There are some specifically polyfill libraries for that purposes:

Hi @mtkennerly. Looking at that list of features NotNullWhen and NotNullWhenAttribute are nice to haves but not a big deal. That said, I have no idea how you could put it on net4.6 without ReadOnlySpan and ReadOnlyMemory those are crucial pieces of the parser and would be very hard to get it working without that.

As for default interfaces those can be fixed. Is there a lib that can emulate ReadOnlySpan on net4.6?

Microsoft has some standalone packages that look like they could work:

• https://www.nuget.org/packages/System.Memory/
  • supports net461
  • says it provides System.ReadOnlySpan and System.ReadOnlyMemory
• https://www.nuget.org/packages/System.Diagnostics.Tools/
  • supports net45
  • says it provides System.Diagnostics.CodeAnalysis.SuppressMessageAttribute, so it might have the NotNull* ones in that namespace as well, but I'm not sure

I got Linguini.Shared working with these dependencies and some minor code changes:

<PackageReference Include="IndexRange" Version="1.0.2" />
<PackageReference Include="Nullable" Version="1.3.0" />
<PackageReference Include="System.Memory" Version="4.5.4" />
<PackageReference Include="TA.System.Runtime.CompilerServices.RuntimeHelpers.GetSubArray" Version="1.0.1" />

I'm working through the errors from the other projects now. I'll report back on how it goes and/or open a PR if I get it working.
