Add frame replacement and removal options

[26fe]

Summary

Adds explicit controls for replacing or removing complete ID3 frame types during NodeID3.update().

This is useful for multiple-value frames such as SYLT, where the existing update behavior appends new values and does not provide a way to replace all existing instances. Calls that omit the new options retain the existing merge behavior.

Changes

• Add replaceFrames and removeFrames update options to NodeID3.update()
• Apply the same behavior to buffer, filepath, callback, synchronous, and promise update APIs.
• Add TypeScript declarations through UpdateOptions.
• Document merge, replacement, and removal behavior in the README.
• Add generated-buffer and disposable-file tests.

Examples

Replace every existing SYLT frame with the supplied synchronized lyrics:

NodeID3.update(
    {
        synchronisedLyrics: [newLyrics]
    },
    fileOrBuffer,
    {
        replaceFrames: ['SYLT']
    }
)

Remove every existing SYLT frame:

NodeID3.update(
    {},
    fileOrBuffer,
    {
        removeFrames: ['SYLT']
    }
)
