Multiple capital letters in title are lowercased and empty space is added in between

Seems multiple capital letters in title are lowercased and empty space is added in between. Tested the sample and noticed the ID has space between. Would assume title remains as written by default.

interface User {
    id: number;
    name: string;
    email: string;
  }

  const schema = ExcelSchemaBuilder.create<User>()
    .column("ID", { key: "id" })
    .column("NAME", { key: "name" })
    .column("Email", { key: "email" })
    .build();

  const users: User[] = [
    {
      id: 1,
      name: "JOHN Doe",
      email: "john@foo.com",
    },
  ];

  const excelFile = ExcelBuilder.create()
    .sheet("Sheet1")
    .addTable({
      data: users,
      schema,
    })
    .build({ output: "buffer", bordered: false });
``

@hixus Thanks for the report, fixed & released with v0.2.12.
When label isn't provided, the lib use the column key as label but previously ran some formatting on the raw key.

It was on the early iterations of the lib, does not seem useful & relevant anymore, I just removed it.

Thanks, works now.
