Cannot download separate attachment files

[aleksandar-manukov]

When there are more than one attachment, we cannot download separate attachment files using:

oss.sdk.net/src/SDK/Services/AttachmentRequirementService.cs

Line 78 in 80a7e68

public DownloadedFile DownloadAttachmentFile(PackageId packageId, String attachmentId, Int32 fileId)

because the path template used in the DownloadAttachmentFile(string packageId, string attachmentId, Int32 fileId) method in the AttachmentRequirementApiClient is wrong:

oss.sdk.net/src/SDK/Services/Internal/AttachmentRequirementApiClient.cs

Line 100 in 80a7e68

string path = template.UrlFor(UrlTemplate.ATTACHMENT_REQUIREMENT_PATH)

Fix: UrlTemplate.ATTACHMENT_REQUIREMENT_PATH -> UrlTemplate.ATTACHMENT_FILE_PATH
