Expand supported hash types

[stevespringett]

Hash support is limited and ambiguous in the case of SHA. CycloneDX is more precise and supports the following:

<xs:simpleType name="hashAlg">
  <xs:restriction base="xs:string">
    <xs:enumeration value="MD5"/>
    <xs:enumeration value="SHA-1"/>
    <xs:enumeration value="SHA-256"/>
    <xs:enumeration value="SHA-384"/>
    <xs:enumeration value="SHA-512"/>
    <xs:enumeration value="SHA3-256"/>
    <xs:enumeration value="SHA3-512"/>
  </xs:restriction>
</xs:simpleType>

<xs:simpleType name="hashValue">
  <xs:restriction base="xs:token">
    <xs:pattern value="([a-fA-F0-9]{32})|([a-fA-F0-9]{40})|([a-fA-F0-9]{64})|([a-fA-F0-9]{96})|([a-fA-F0-9]{128})"/>
  </xs:restriction>
</xs:simpleType>

It also supports simple validation of the field as well, although complex validation (e.g. SHA-512 alg with only 40 characters) is not supported.
