Incompatable with CSVHelper v30

[marshallwp]

Describe the bug CsvHelper.Excel v27.2.1 is incompatable with CSVHelper v30.0.0. Specifically, some of the breaking changes in that version add: bool LeaveOpen { get; } to IWriterConfiguration and IParserConfiguration. This causes CsvHelper.Excel to throw a System.MissingMethodException when trying to open an Excel file (at least via the MemoryStream method described below).

System.MissingMethodException: Method not found: 'Boolean CsvHelper.Configuration.IParserConfiguration.get_LeaveOpen()'.
   at CsvHelper.Excel.ExcelParser..ctor(Stream stream, String sheetName, CsvConfiguration configuration)

To Reproduce Steps to reproduce the behavior:

FileStreamOptions readOnly = new FileStreamOptions(){Mode = FileMode.Open, Access = FileAccess.Read, Share = FileShare.ReadWrite};
CsvConfiguration ExcelConfig = new CsvConfiguration(CultureInfo.InvariantCulture){ 
	 IgnoreBlankLines = true
	,ShouldSkipRecord = args => args.Row.Parser.Record.All(string.IsNullOrWhiteSpace)
	,HasHeaderRecord = true
};

MemoryStream ms = new();
using(FileStream fileStream = new FileStream("path/to/file.xlsx", readOnly)) { fileStream.CopyTo(ms); }

using(CsvReader rdr1 = new CsvReader(new ExcelParser(ms,"Sheet1",ExcelConfig))) // <- Error occurs here
using(CsvReader rdr2 = new CsvReader(new ExcelParser(ms,"Sheet2",ExcelConfig)))
{
	var results1 = rdr1.GetRecords<dynamic>();
	var results2 = rdr2.GetRecords<dynamic>();
}

Expected behavior Program runs without issue.

Versions (please complete the following information):

• CSVHelper: 30.0.0
• CSVHelper.Excel.Core: 27.2.1
