Add boundary tests for BinaryCodec.fromAscii partial-bit inputs

[pdtx]

Summary

• Add boundary tests for BinaryCodec.fromAscii(byte[]) and BinaryCodec.fromAscii(char[]) when input length is less than 8 bits.
• Add boundary tests for non-multiple-of-8 input lengths to assert the current decoding behavior where extra leading bits are ignored.
• Add a direct null-contract test for BinaryCodec.toAsciiString(byte[]).

Why

Current tests cover null/empty and exact 8-bit aligned inputs, but do not explicitly cover short non-empty inputs or partial-bit-length inputs.
These boundary cases are easy to regress (for example, through off-by-one or grouping changes), so explicit tests improve behavioral stability.

Verification

• Ran mvn -Dtest=BinaryCodecTest test
• Result: all tests passed

Hello @pdtx

Thank you for your PR.

Update the existing testFromAsciiCharArray(), testFromAsciiByteArray(), and testToAsciiString().

Thank you!

[garydgregory]

Make this edge case the first assertion in testToAsciiString().

[pdtx]

Thanks for the review. Updated as requested: I folded the new assertions into the existing testFromAsciiCharArray(), testFromAsciiByteArray(), and testToAsciiString() methods, and removed the standalone test methods.

Thanks for the note. Rebased on the latest master, resolved conflicts, and force-pushed the branch.
