[REQ][typescript-angular] Option to rename ApiModule and Configuration

Created by: snebjorn

Is your feature request related to a problem? Please describe.

Generated angular client module will always be called ApiModule. The module also exposes a Configuration object which also cannot be renamed.

This isn't great when multiple generated clients are needed in a single project.

Describe the solution you'd like

I'd like an Config Option for typescript-angular that can configure the Module and Configuration prefix.

Option	Description	Values	Default
modulePrefix	The prefix of the file and class of the generated module (<prefix>.module.ts and class <prefix>Module).		Api
configuraionPrefix	The prefix of the file and class of the generated configuration object (<prefix>Configuration.ts and class <prefix>Configuration).		null

Note the names are in the default fileNaming: camelCase format, but kebab-case should also be supported
