v3.7.1

Added

• ValueStringBuilder interpolated strings support alignment holes such as $"{value,10}" and $"{value,-10:F2}", like FixedSizeValueStringBuilder.
• ValueStringBuilder.Append(char value, int repeatCount).

Changed

• Any ISpanFormattable value type (not only the built-in well-known ones) is formatted without boxing in interpolated strings, AppendJoin, Concat, AppendFormat and ReplaceGeneric.
• Append<T> for ISpanFormattable values first formats into the remaining buffer and only grows when the value does not fit, instead of reserving 36 characters up front.
• AppendJoin with an IEnumerable<T> that is an array or List<T> no longer allocates an enumerator.
• Growing the buffer is moved out of the inlined Append fast paths, which makes them smaller.
• Append(char) does a single bounds check per character (about 40% faster in a tight loop).
• AppendJoin and friends dispatch value types through a small inlinable helper instead of a 20-entry type table, which the JIT could not inline in deep call chains (AppendJoin over ints about 40% faster).
