fix: actually fetch all the objects from S3

[LoneRifle]

This driver currently fetches only the first 1000 blocks for a given file, the default behaviour for S3's listObjectsV2():

wa-sqlite-s3vfs/src/s3vfs.ts

Lines 108 to 111 in c054d1a

	const { Contents: objects } = await this.s3.listObjectsV2({
	Bucket: this.bucketName,
	Prefix: `${prefix}/`,
	})

This should be modified to fetch all objects
